MSCC LED Opportunity
 .  Blue/White LED Market Opportunity
   -  24% CAGR for the InGaN market through 2005
   -  Emergence of Blue/White applications in mobile devices growing rapidly
 .  Why Microsemi chose LED market? Market need! NEGLECTED end-users
   -  No system solutions, lack of unique drive techniques, packaging/heat
      issues
   -  Epoxy degradation, reliability problems, discoloration, inconsistency,
      etc.

What sets us apart?
 . Experience Driving Light
  -  History
     --  Patented digital dimming for CCFL solutions
     --  Solved temperature problems for automotive customers
     --  Solved power efficiency problems for mobile customers on battery life
  -  Dominant products on CCFL
     --  50% more efficient than comparable technologies
     --  Reduce component count by half
  -  Total engineered system level solution
     --  No one in the market understands the system
     --  Maximized expertise is power management, packaging, and drive
         architecture
 . Packaging Expertise
  -  Biggest problem today in LEDs is HEAT
     --  We have packaging technology to get heat out of the package
     --  Competition doesn't understand this, and disconnected- who's job is it?
     --  Discrete devices that we have decades of experience with dealing heat
         dissipation

Advantages of Approach
 .    Inexpensive Silicon Substrate: Silicon starting substrates are less
     expensive than SiC or sapphire. They allow larger wafer diameters.
 .    Larger chips/Less defect densities: Our device technology is built on
     silicon, we can make larger chips with less defects
 .    Eliminates Epoxy Issues: Eliminates epoxy packaging with a hermetic wafer
     scale LED
 .    Improved Thermal Resistance: Thermal resistance in the MMSM is near zero
     (Handles 10 watts of RF incident power today) enabling the ability to drive
     LEDs at much higher power.
 .    Better Parasitic resistance: Improved to under 0.2pF coupled together with
     Nitronex advanced EPI growth know-how can deliver LED VF 3.2Volts!

MSCC Approach
1    Optomite
     .    Current product- Time to market is fast
     .    Superior thermal efficiency- Addresses current need
          -  100C/Watt vs. 380C/W and 700C/W
     .    Improve epoxy degradation
     .    Chip agnostic- Initially using Cree MB
2    MMSM
     .    Ultimate device
     .    GaN on Si - 4"wafers gives economies of scale
     .    Eliminate epoxy degradation
     .    Flip chip, hermetic, lower Vf, thermal dissipation high

Slide 14

What Is An LED?
 .  Voltage applied across device allows electrons to move across the junction
   between the n and p regions.
 .  Once in the p region the electrons are immediately attracted to the
   positive charges due to the mutual Coulomb forces.
 .  When an electron moves sufficiently close to a positive charge in the p
   region, the two charges "re-combine".
 .  Recombination converts potential energy to Quantum electromagnetic energy
   (Photon) with a specific frequency.

How To Drive An LED

 .  Drive Voltage Must Exceed Or Equal LED V\\F\\ (Forward Voltage)
 .  Drive Currents (IAVG) Must Not Exceed Rating
 .  LEDs Require a Current Source (What does that mean?)
 .  Blue/White LEDs Have A VF = 4.0V
[schematic] Rc, V greater than or equal to VF, 1LED = V - VF Rc

Slide 21

Parallel Drive Drawbacks

 .  Current/Light Matching Variation
   - Currently white LEDs have a typical forward voltage (VF) of 3.6V and a
     maximum VF of 4.0V. Low temperature operation can further raise the maximum
     VF to 4.2V. Drive current variations also affect VF.
   - LEDs have a linear relationship of current vs. light intensity. Given VF
     variation, light intensity variations of over 40% may be experienced in a
     given application.
 .  Efficiency Degradation
   - Since a current limiting resistor is required for LED drive circuits, then
     a power loss is experienced across this resistor on the order of 31mW for
     series drive and 125mW for parallel drive. Series configuration offers a
     25% improvement in the efficiency calculation.

Slide 22

Series Drive Drawbacks
Inductor Boost
 .  Cost
 .  Switching Noise
 .  More Complex Design
 .  Output Voltage Clamp Recommended
   - If the load is disconnected for any reason, then the FB pin is rounded
     causing the output voltage to climb until components fail.
