MULTIPHASE CONVERTER WITH PHASE INTERLEAVING

Title:

MULTIPHASE CONVERTER WITH PHASE INTERLEAVING

Document Type and Number:

WIPO Patent Application WO/2018/136215

Kind Code:

A3

Abstract:

A multiphase power converter (200) includes power channels arranged in parallel to drive an output of the power converter, and a channel selection circuit (118). Each of the power channels includes a driver (108), a feedback control circuit (210) coupled to an output of the driver (108), and a comparator (208) coupled to the feedback control circuit (210). The channel selection circuit (118) is coupled to the feedback control circuit (210) of each of the power channels. The channel selection circuit (118) is configured to: select a different specific one of the power channels to activate in each of multiple phases, and introduce an offset voltage into each of the feedback control circuits (210), except the feedback control circuit (210) of the specific one of the power channels. The feedback control circuit (210) is configured to apply the offset to bias driver output feedback voltage away from a threshold voltage at which the power channel is activated.
