<p>A multiphase power supply that minimizes losses during a low power model. In a particular embodiment, a multiphase power supply may include a plurality of switching regulators 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. The phase 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 with respect 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 of switching regulators by removing or disabling at least one of the plurality of control signals to each of the subset of switching regulators.</p> |
