Abstract
A digital current-mode controller for a DC-DC converter is disclosed. The controller comprises a digital current reference; and a current loop compensator adapted to receive a digital current error signal derived from a digital current sample sensed from the DC-DC converter and the digital current reference and to generate a duty-cycle command, wherein the current loop compensator comprises a low-pass filter that is used in generating the duty-cycle command. A DC-DC regulator comprising a digital current-mode controller and a method of controlling a DC-DC converter are also disclosed.
