Abstract
Systems and methods are disclosed to control a buck converter by performing adaptive digital pulse width modulation (ADPWM) with a plurality of upper power transistors each uniquely controlled to enable greater than 100% duty cycle for the buck converter and a lower power transistor coupled to the plurality of upper power transistors; and driving an inductor having one end coupled to the lower power transistor and the upper power transistors.
