SYSTEMS AND METHODS FOR MAXIMIZING MULTI-PHASE VOLTAGE REGULATOR EFFICIENCY USING OPERATIONAL MODES IN WHICH PHASES OPERATE IN FULLY-ENABLED MODE AND LIGHT-LOAD MODE
SYSTEMS AND METHODS FOR MAXIMIZING MULTI-PHASE VOLTAGE REGULATOR EFFICIENCY USING OPERATIONAL MODES IN WHICH PHASES OPERATE IN FULLY-ENABLED MODE AND LIGHT-LOAD MODE
A method may include operating a power system coupled to at least one information handling resource, configured to provide electrical energy to the at least one information handling resource, and comprising a plurality of voltage regulator phases, in a plurality of operational modes, each mode defining a number of the plurality of voltage regulator phases operating in a fully-enabled mode and whether or not one of the plurality of voltage regulator phases operates in a light-load mode, selecting a selected operational mode from the plurality of operational modes based on a load requirement of the at least one information handling resource, and controlling the plurality of voltage regulator phases to deliver an aggregate current in accordance with the load requirement and the selected operational mode.
