Peak-buck Peak-boost Current-mode Control for Switched Step-up Step-down Regulators
22 Jul 21
A peak-buck peak-boost current mode control structure and scheme for a synchronous four-switch and non-synchronous two-switch buck-boost regulators sense input and output voltages to smoothly transition between buck mode, buck-boost mode, and boost mode for high power efficiency and low output ripples.
