Organization, Consolidation and Presentation of Financial Statements Disclosure [Text Block] | 1. BASIS OF PRESENTATION | ||
The accompanying unaudited condensed consolidated financial statements have been prepared by Monolithic Power Systems, Inc. (the “Company” or “MPS”) in accordance with the rules and regulations of the Securities and Exchange Commission (the “SEC”). Certain information and disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States (“GAAP”) have been condensed or omitted in accordance with these rules and regulations. The information in this report should be read in conjunction with the Company’s audited consolidated financial statements and notes thereto included in the Annual Report on Form 10-K for the year ended December 31, 2014, filed with the SEC on March 2, 2015. | |||
In the opinion of management, the accompanying unaudited condensed consolidated financial statements reflect all adjustments (consisting only of normal recurring adjustments) necessary to present fairly the Company’s financial position, results of operations and cash flows for the interim periods presented. The financial statements contained in this Form 10-Q are not necessarily indicative of the results that may be expected for the year ending December 31, 2015 or for any other future periods. | |||
Summary of Significant Accounting Policies | |||
There have been no changes to the Company’s significant accounting policies during the three months ended March 31, 2015 as compared to the significant accounting policies described in the Company’s audited consolidated financial statements included in the Annual Report on Form 10-K for the year ended December 31, 2014. | |||
Recent Accounting Pronouncements | |||
In May 2014, the Financial Accounting Standards Board ("FASB") issued Accounting Standards Update No. 2014-09, Revenue from Contracts with Customers, which outlines a single comprehensive model for entities to use in accounting for revenue arising from contracts with customers. The standard’s core principle is that an entity will recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the entity expects to be entitled in exchange for those goods or services. Under the new standard, entities will apply the following five-step model when evaluating revenue contracts with customers: | |||
● | Identify the contract with a customer | ||
● | Identify the performance obligations in the contract | ||
● | Determine the transaction price | ||
● | Allocate the transaction price to the performance obligations in the contract | ||
● | Recognize revenue when the entity satisfies a performance obligation | ||
The standard as currently issued will be effective for the Company starting in the first quarter of fiscal 2017. In April 2015, the FASB voted to propose a one-year deferral to the effective date, but to permit entities to adopt one year earlier if they choose (i.e., the original effective date). The proposal is subject to the FASB’s due process requirement, which includes a period for public comments. Entities have the option of using either a full retrospective or a modified retrospective application in the adoption of this standard. The Company is evaluating the transition method and the impact of the adoption on its consolidated financial position, results of operations and cash flows. |

Business Combinations [Abstract] | |||||
Business Combination Disclosure [Text Block] | 3. ACQUISITION | ||||
On July 22, 2014 (the “Acquisition Date”), the Company acquired 100% of the outstanding capital stock of Sensima Technology SA (“Sensima”), a company based in Switzerland that develops magnetic sensor technologies for angle measurements as well as three-dimensional magnetic field sensing. The acquisition is expected to create new opportunities with customers by offering enhanced solutions in power management for key industries such as automotive, industrial and cloud computing. As a result of the acquisition, Sensima became a subsidiary of the Company and its results of operations have been included in the Company’s consolidated financial statements subsequent to the acquisition. | |||||
Purchase Consideration | |||||
The fair value of the purchase consideration consists of the following (in thousands): | |||||
Cash paid at the Acquisition Date | $ | 11,735 | |||
Contingent consideration | 2,507 | ||||
Total | $ | 14,242 | |||
Cash paid at the Acquisition Date included $1.2 million that is being held in an escrow account for a one-year period, which is subject to Sensima’s satisfaction of certain representations and warranties. | |||||
The contingent consideration arrangement requires the Company to pay up to an additional $8.9 million to former Sensima shareholders if Sensima achieves a new product introduction as well as certain product revenue and direct margin targets in 2016. The fair value of the contingent consideration at the Acquisition Date was $2.5 million, which was estimated based on a probability-weighted analysis of possible future cash flow outcomes. The fair value of the contingent consideration is recorded in other long-term liabilities in the Condensed Consolidated Balance Sheets and is remeasured at the end of each reporting period, with any changes in fair value recorded in operating expense in the Condensed Consolidated Statements of Operations. Actual amounts that will ultimately be paid may differ from the obligations recorded. | |||||
The Company incurred $0.6 million of transaction costs that were expensed as incurred. | |||||
Preliminary Purchase Consideration Allocation | |||||
The estimated fair value of assets acquired and liabilities assumed is as follows (in thousands): | |||||
Cash | $ | 145 | |||
Other tangible assets acquired, net of liabilities assumed | 42 | ||||
Intangible assets: | |||||
Know-how | 1,018 | ||||
Developed technologies | 4,421 | ||||
IPR&D | 2,045 | ||||
Total identifiable net assets acquired | 7,671 | ||||
Goodwill | 6,571 | ||||
Total net assets acquired | $ | 14,242 | |||
Intangible assets with finite lives include know-how and developed technologies with estimated useful lives of three to five years. The fair value of know-how was determined using the relief from royalty method, and the fair value of the developed technologies was determined using the income approach. Intangible assets with indefinite lives include IPR&D, which consists of incomplete R&D projects that had not reached technological feasibility as of the Acquisition Date. The fair value of the IPR&D assets was determined using the income approach. | |||||
The goodwill arising from the acquisition was primarily attributed to synergies which will enable the Company to develop advanced solutions in power management by combining with Sensima’s magnetic sensor technologies. The goodwill is not expected to be deductible for tax purposes. | |||||
The purchase price allocation is considered preliminary and dependent upon the finalization of the valuation of assets acquired and liabilities assumed, primarily related to deferred taxes. The Company is currently determining if the acquisition qualifies as a tax-free reorganization within the meaning of Swiss tax rules pursuant to the tax holiday granted to Sensima by the Swiss tax authorities. Final determination of the valuation could result in an adjustment to the preliminary purchase price allocation, with an offsetting adjustment to goodwill. | |||||
Equity Awards | |||||
On the Acquisition Date, the Board of Directors granted $1.7 million of time-based RSUs (or 40,000 shares) to key Sensima employees who became employees of the Company. These awards vest over four years. In addition, the Board of Directors granted $2.0 million of PSUs (or 47,000 shares) to these employees, with the right to earn up to a maximum of $8.0 million based on the achievement of certain cumulative Sensima product revenue targets during the performance period from the Acquisition Date to July 22, 2019. One half of the awards subject to each revenue goal will vest immediately when the pre-determined revenue goal is met and approved by the Compensation Committee, and the remaining 50% will vest over the following two years. The vesting is subject to the employees’ continued employment with the Company. These equity awards are considered arrangements for post-acquisition services and the related compensation expense is being recognized over the requisite service period. | |||||
Pro Forma Information (Unaudited) | |||||
Supplemental information of the Company’s results of operations on a pro forma basis, as if the Sensima acquisition had been consummated on January 1, 2014, is presented as follows (in thousands, except per-share amounts): | |||||

Earnings Per Share [Abstract] | |||||||||
Earnings Per Share [Text Block] | 6. NET INCOME PER SHARE | ||||||||
Basic net income per share is computed by dividing net income by the weighted average number of common shares outstanding for the period. Diluted net income per share reflects the potential dilution that would occur if outstanding securities or other contracts to issue common stock were exercised or converted into common stock, and calculated using the treasury stock method. | |||||||||
The Company’s outstanding RSUs contain forfeitable rights to receive dividend equivalents, which are accrued quarterly during the vesting periods of the RSUs and are payable to the employees when the awards vest. Dividend equivalents accrued on the RSUs are forfeited if the employees do not fulfill their service requirement during the vesting periods. Accordingly, these awards are not treated as participating securities in the net income per share calculation. | |||||||||
The following table sets forth the computation of basic and diluted net income per share (in thousands, except per-share amounts): | |||||||||

For the three months ended March 31, 2015, approximately 24,000 common stock equivalents were excluded from the calculation of diluted net income per share because their inclusion would have been anti-dilutive. For the three months ended March 31, 2014, there were no anti-dilutive common stock equivalents. |

Segment Reporting Disclosure [Text Block] | 7. SEGMENT AND GEOGRAPHIC INFORMATION | ||||||||||||||||
The Company operates in one reportable segment that includes the design, development, marketing and sale of high-performance, mixed-signal analog semiconductors for the communications, storage and computing, consumer and industrial markets. The Company’s chief operating decision maker is its chief executive officer, who reviews financial information presented on a consolidated basis. The Company derives a majority of its revenue from sales to customers located outside North America, with geographic revenue based on the customers’ ship-to locations. | |||||||||||||||||
The Company sells its products primarily through third-party distributors, value-added resellers and directly to original equipment manufacturers, original design manufacturers, and electronic manufacturing service providers. The following table summarizes those customers with sales greater than 10% of the Company's total revenue or accounts receivable balances greater than 10% of the Company’s total accounts receivable: | |||||||||||||||||

Both of the customers are third-party distributors. The Company’s agreements with these distributors were made in the ordinary course of business and may be terminated with or without cause by these distributors with advance notice. Although the Company may experience a short-term disruption in the distribution of its products and a short-term decline in revenue if its agreement with either of these distributors was terminated, the Company believes that such termination would not have a material adverse effect on its financial statements because it would be able to engage alternative distributors, resellers and other distribution channels to deliver its products to end customers within a few quarters following the termination of an agreement with a distributor. | |||||||||||||||||

Legal Matters and Contingencies [Text Block] | 8. LITIGATION |
The Company and certain of its subsidiaries are parties to actions and proceedings in the ordinary course of business, including litigation regarding its shareholders and its intellectual property, challenges to the enforceability or validity of its intellectual property, claims that the Company’s products infringe on the intellectual property rights of others, and employment matters. These proceedings often involve complex questions of fact and law and may require the expenditure of significant funds and the diversion of other resources to prosecute and defend. The Company defends itself vigorously against any such claims. | |
O2 Micro | |
In May 2012, the United States District Court for the Northern District of California (the “District Court”) issued an order finding O2 Micro International, Ltd. (“O2 Micro”) liable for approximately $9.1 million in attorneys’ fees and non-taxable costs, plus interest, in connection with the patent litigation that the Company won in 2010. This award was in addition to the approximately $0.3 million in taxable costs that the District Court had earlier ordered O2 Micro to pay to the Company in connection with the same lawsuit. In October 2012, O2 Micro appealed the District Court’s judgment to the United States Court of Appeals for the Federal Circuit (the “Federal Circuit”). In August 2013, the Federal Circuit affirmed O2 Micro’s liability for the full amount of the award. In September 2013, O2 Micro filed a petition for rehearing of that ruling, but the Federal Circuit denied O2 Micro’s petition for rehearing in October 2013. | |
In November 2013, the Company received a cash payment of $9.5 million from O2 Micro. In January 2014, O2 Micro filed an appeal with the United States Supreme Court. Had O2 Micro been successful in obtaining a favorable ruling against the Company, the Company could have been liable to return a portion or all of the $9.5 million to O2 Micro. Accordingly, the Company recorded the $9.5 million as a current liability as of December 31, 2013. | |
In March 2014, the Supreme Court declined to hear the case. As O2 Micro had no further legal avenues to appeal, the Company released the current liability of $9.5 million and recorded the award as a litigation benefit in the Condensed Consolidated Statements of Operations in the first quarter of 2014. In addition, the Company incurred additional legal fees of $0.5 million in connection with the final resolution of the lawsuit. |

Income Tax Disclosure [Text Block] | 12. INCOME TAXES |
The income tax provision for the three months ended March 31, 2015 was $0.5 million, or 8.2% of the income before income taxes. This differs from the federal statutory rate primarily because the Company’s foreign income was taxed at lower rates, and because of the benefit that the Company realized as a result of stock option exercises, the release of RSUs and changes in the valuation allowance. | |
The income tax provision for the three months ended March 31, 2014 was $0.3 million, or 2.8% of the income before income taxes. This differs from the federal statutory rate primarily because the Company’s foreign income was taxed at lower rates, and because of the benefit that the Company realized as a result of stock option exercises, the release of RSUs and changes in the valuation allowance. | |
Unrecognized Tax Benefits | |
As of March 31, 2015, the Company had $16.7 million of unrecognized tax benefits, $5.0 million of which would affect its effective tax rate if recognized after considering the valuation allowance. As of December 31, 2014, the Company had $16.4 million of unrecognized tax benefits, $4.8 million of which would affect its effective tax rate if recognized after considering the valuation allowance. | |
Uncertain tax positions relate to the allocation of income and deductions among the Company’s global entities and to the determination of the research and development tax credit. It is reasonably possible that over the next twelve-month period, the Company may experience increases or decreases in its unrecognized tax benefits. However, it is not possible to determine either the magnitude or the range of increases or decreases at this time. | |
The Company recognizes interest and penalties, if any, related to uncertain tax positions in its income tax provision. As of March 31, 2015 and December 31, 2014, the Company has approximately $0.5 million of accrued interest related to uncertain tax positions, which were recorded in long-term tax liabilities in the Condensed Consolidated Balance Sheets. | |
Income Tax Audits | |
The Company is subject to examination of its income tax returns by the IRS and other tax authorities. The Company’s U.S. Federal income tax returns for the years ended December 31, 2005 through December 31, 2007 are under examination by the IRS. In April 2011, the Company received from the IRS a Notice of Proposed Adjustment ("NOPA") relating to a cost-sharing agreement entered into by the Company and its international subsidiaries on January 1, 2004. In the NOPA, the IRS objected to the Company’s allocation of certain litigation expenses between the Company and its international subsidiaries and the amount of "buy-in payments" made by the international subsidiaries to the Company in connection with the cost-sharing agreement, and proposed to increase the Company’s U.S. taxable income according to a few alternative methodologies. In February 2012, the Company received a revised NOPA from the IRS (“Revised NOPA”). In this Revised NOPA, the IRS raised the same issues as in the NOPA issued in April 2011 but under a different methodology. Under the Revised NOPA, the largest potential federal income tax payment, if the IRS were to prevail on all matters in dispute, is $10.5 million, plus interest and penalties, if any. The Company responded to the IRS Revised NOPA in May 2012. In June 2013, the IRS responded and continued to disagree with the Company’s rebuttal. The Company met with the IRS Office of Appeals in 2014, had additional discussions again in 2015, and both parties have been in continuous discussions for a resolution of the matter. However, there is no guarantee these discussions will be conclusive. Meanwhile, the Company agreed to grant the IRS an extension of the statute of limitations for taxable years 2005 through 2007 to September 30, 2015. | |
The IRS also audited the research and development credits carried forward into year 2005 and the credits generated in the years 2005 through 2007. The Company received a NOPA from the IRS in February 2011, proposing to reduce the research and development credits generated in years 2005 through 2007 and the carryforwards, which would then reduce the value of such credits carried forward to subsequent tax years. | |
Subsequent to March 31, 2015, the Company reached a final resolution with the IRS in connection with the income tax audits. See Note 16 for further discussion of the subsequent event. |

Dividends And Dividend Equivalents [Text Block] | 15. DIVIDENDS AND DIVIDEND EQUIVALENTS |
In June 2014, the Board of Directors approved a dividend program pursuant to which the Company intends to pay quarterly cash dividends on its common stock. Stockholders of record as of the last day of the quarter are entitled to receive the quarterly cash dividends when and if declared by the Board of Directors, which are generally payable on the 15th of the following month. For the first quarter of 2015, the Board of Directors declared a dividend of $0.20 per share for a total of $7.9 million, which was accrued as of March 31, 2015 and will be paid to the stockholders on April 15, 2015. | |
The declaration of any future cash dividends is at the discretion of the Board of Directors and will depend on the Company's financial condition, results of operations, capital requirements, business conditions and other factors, as well as a determination that cash dividends are in the best interests of the Company's stockholders. The Company anticipates that the cash used for future dividends will come from its current domestic cash and cash generated from ongoing U.S. operations. If cash held by the Company’s international subsidiaries is needed for the payment of dividends, the Company may be required to accrue and pay U.S. taxes to repatriate the funds. | |
Under the Company’s stock plans, outstanding RSU awards contain rights to receive cash dividend equivalents, which entitle employees who hold RSUs to the same dividend value per share as holders of common stock. The dividend equivalents are accrued quarterly during the vesting periods of the RSUs and are payable to the employees when the awards vest. Dividend equivalents accrued on the outstanding RSUs are forfeited if the employees do not fulfill their service requirement during the vesting periods. As of March 31, 2015 and December 31, 2014, accrued dividend equivalents totaled $1.4 million and $0.8 million, respectively. |

Stock Repurchase Program | |
In April 2015, the Board of Directors approved an extension of the stock repurchase program to December 31, 2015. No other terms were amended under the program. | |
Income Tax Audits | |
In April 2015, the Company reached a final resolution with the IRS in connection with the income tax audits for the years 2005 through 2007. Under the agreement, the Company made a one-time buy-in payment of $1.2 million for taxes related primarily to the revaluation of a license for certain intellectual property rights of the Company to one of its international subsidiaries. This buy-in payment is final and no additional payment will be required with respect to the intellectual property license for the years under examination or for a previous or subsequent tax year. In addition, the Company expects to make a $1.1 million related interest payment in the next few months as well as a $0.2 million tax payment for the years 2008 to 2013. There were no penalties assessed on the Company as a result of the audits. | |
For the second quarter of 2015, the Company's income tax provision will include a one-time net charge of approximately $2.3 million, reflecting the taxes and interest to be paid partially offset by the reversal of previously accrued tax liabilities and valuation allowances. Of the $2.3 million charge, approximately $1.6 million relates to taxes and $0.7 million to interest. |
