Abstract

A multi-phase power converter includes a plurality of power channels arranged in parallel to drive an output of the power converter, and a channel selection circuit. Each of the power channels includes a driver, a feedback control circuit coupled to an output of the driver, and a comparator coupled to the feedback control circuit. The channel selection circuit is coupled to the feedback control circuit of each of the power channels. The channel control circuit is configured to: select a different specific one of the power channels to activate in each of a plurality of phases, and introduce an offset voltage into each of the feedback control circuits, except the feedback control circuit of the specific one of the power channels. The feedback control circuit is configured to apply the offset to bias driver output feedback voltage away from a threshold voltage at which the power channel is activated.
