Abstract:
The high side or low side FET of a buck converter, or both, are replaced by plural parallel devices of different threshold voltage and are turned on and off in a sequence which offers the best turn on and turn off characteristics related to high and low threshold voltages. The parallel devices can have the same or different active areas.
