Abstract

A voltage regulator circuit comprises a plurality of voltage regulator phases, a first load output coupled to the plurality of voltage regulator phases for providing a first output voltage, a first coupling inductor having a first winding and a second winding, the first winding coupled in series between a first voltage regulator phase of the plurality of voltage regulator phases and the first load output, a second load output coupled to the second winding for providing a second output voltage, and a first switch coupled in series with the second winding. A method comprises detecting a startup event; determining an installed processor type; retrieving a configuration parameter value; providing a first output voltage at a first load output; providing, at a second load output coupled to the second winding, a second output voltage; and controlling a first duty cycle of a first switch coupled in series with the second winding.
