Abstract:
1. In an information handling system, a method for generating a regulated direct current (DC) voltage output of a voltage regulator module (VRM) to power a device of the information handling system, the method comprising: receiving an activity input indicative of levels of activity of a processor included in the device; selecting a first switching frequency from a plurality of switching frequencies of the VRM, the first switching frequency corresponding to a first level of activity; receiving a DC voltage input; generating a switched DC voltage output having the first switching frequency; and filtering the first switching frequency from the switched DC voltage output to generate the regulated DC voltage output, wherein the first level of activity corresponds to a processor usage level of less than or equal to 30% of a maximum value, and wherein the first switching frequency is approximately 300 kilohertz.
