Abstract:
1. A multi-phase modulator for a multi-phase power converter comprising a multi-phase power converter comprising a plurality of power converter phases; a decoder that receives a digital input command and determines a first number of phases of the plurality of power converter phases to place in a first state based upon the digital input command, the decoder generating a plurality of logic signals corresponding to the first number of phases based upon the digital input command; and a selector that identifies a first set of phases of the plurality of power converter phases to assign to the first state and a second set of phases of the plurality of power converter phases to assign to a second state, wherein the selector comprises a plurality of multiplexers and each of the plurality of multiplexers comprising an input coupled to receive one of the plurality of logic signals and an output coupled to one of the plurality of power converter phases.
