N2 - DC-DC converters are required to supply various levels of voltages from batteries to different systems. In order to extend the lifetime of battery, it is very important to optimize the efficiency of the DC-DC converter, especially the light load efficiency. In this paper, considerations of the efficiency variation of a PWM synchronous buck-boost converter are made to minimize the power loss. Several new techniques such as channel width regulation, variable threshold voltage, switch activation and gate charge modulation are used. Simulation results show that the efficiency can be improved by more than 15% when the converter works on its light load.
