Patent ID: 8125200

Claim:
A method for regulating voltage in an information handling system, comprising: providing DC/DC voltage regulation circuitry comprising multiple power processing circuits coupled to independently supply power to multiple system load components of said information handling system, each power processing circuit of said DC/DC voltage regulation circuitry comprising one or more drive transistors configured to independently supply power to one of the multiple system loads of the information handling system at a different voltage from power simultaneously supplied by the other of said power processing circuits to the other system loads of the information handling system; regulating in a centralized manner from a common source the power supplied by said DC/DC voltage regulation circuitry to said system load components of said information handling system by causing the gate of said one or more drive transistors of each of said power processing circuits to be driven with two or more different gate drive voltage levels; determining two or more real time operating efficiency values of each of said power processing circuits while said power processing circuit is driven at each of two or more respective gate drive voltage levels; and varying the value of said gate drive voltage level used to drive the gate of said one or more drive transistors of each of said power processing circuits based on a comparison of said determined two or more real time operating efficiency values of said power processing circuit.
