PHASE SHEDDING BASED ON PHASE EFFICIENCY DETERMINED BY PULSE WIDTH MODULATOR SWITCHING OF VOLTAGE REGULATOR FIELD EFFECT TRANSISTORS

摘要

A method of operating a multiphase power supply includes identifying a least efficient phase of a plurality of phases in the multiphase power supply based on a comparison of a pulse width for each phase in the plurality of phases, and decreasing an amount of power supplied to a load by the identified least efficient phase.
