Abstract
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. With the inductor current sensing, the control scheme achieves the best performance in continuous conduction and discontinuous condition mode operations.
