Abstract

A system that includes a regulator unit is disclosed. The regulator unit includes first and second phase units whose outputs are coupled to through first and second coupled inductors, respectively, to a power supply node of a circuit block. The first phase unit may be configured to discharge, for a first period of time, the power supply node through the first inductor in response to determining a sense current is greater than a demand current. The operation of the second phase unit may follow that of the first phase unit after a second period of time has elapsed.
