Abstract
A method may comprise receiving a first clock signal; receiving a digital duty cycle value; using the first clock signal and digital duty cycle value to generate a digital pulse width modulation (DPWM) signal having a plurality of discrete steps to control a switch of a switched-mode power supply; and using a voltage control circuit to modify a duration of each of the plurality of discrete steps of the DPWM signal, wherein the voltage control circuit is configured to receive an analog voltage input.
