Large input voltage range and wide output current range are usually needed for dc–dc converters. For these input and output conditions, the converter’s efficiency can be maximized by a proposed method, efficiency-optimized switching-frequency (EOF) control. The optimal switching frequency for maximizing the efficiency is generated by the low-complexity and low-power EOF generator. …
