摘要：A multiphase power supply that minimizes losses during a low power mode+. Ina particular embodiment, a multiphase power supply may include a plurality of switchingregulators coupled in parallel with respect to one another. The multiphase power supply
further comprises a phase control circuit coupled to each of the switching regulators. Thephase control circuit is configured to generate a plurality of control signals for
controlling the switching of the switching regulators so that they are out of phase withrespect to one another. During the low power mode of operation of the microprocessor,the phase control circuit is configured to selectively suspend operation of a subset ofswitching regulators by removing or disabling at least one of the plurality of controlsignals to each of the subset of switching regulators.
