ABSTRACT:
Stepwise drivers for DC/DC converters are described herein. In one embodiment, a stepwise driver is provided to charge or discharge a gate capacitance of a power switch of a DC/DC converter. In a particular embodiment, a stepwise driver example includes multiple switching elements to sequentially switch to charge a gate capacitance of a power switch of a DC/DC converter from a first voltage to a second voltage in multiple steps. Other methods and apparatuses are also described.
