Abstract
A controller circuit for a switch-mode power supply (SMPS). The controller circuit is configured to generate, with a plurality of phases, a combined output current at a supply node to supply a load, determine a ripple shaping current complimentary to an estimated ripple at the combined output current using a number of active phases of the plurality of phases that generate the combined output current, and generate, with an auxiliary phase, the ripple shaping current at the supply node to reduce ripple occurring at the combined output current.
