Patent ID: 8917074

Claim:
A voltage regulator, comprising: a high-side power transistor; a low-side power transistor, wherein the high-side power transistor and the low-side power transistor are operable to output power to a transient load, and wherein the high-side power transistor and the low-side power transistor comprise enhanced metal-oxide-semiconductor field-effect transistors (“MOSFETs”); control circuitry coupled to the high-side power transistor, the low-side power transistor, and the transient load, wherein the control circuitry is operable to receive a control signal from the transient load, wherein the control signal corresponds to an operating voltage of the transient load, wherein the control signal comprises a voltage identification (“VID”) signal generated at the processor; wherein the transient load comprises a processor in an information handling system; wherein the control circuitry comprises a regulator controller and a driver; wherein in response to a decrease in a power level required by the transient load, the control circuitry is operable to turn off the high-side power transistor, turn on the low-side power transistor for at least one first duration, and turn off the low-side power transistor for at least one second duration, wherein the at least one first duration and the at least one second duration are based, at least in part, on the operating voltage; and wherein the at least one first duration and the at least one second duration correspond to a predetermined switching pattern, wherein the predetermined switching pattern corresponds to an operating voltage identified by the voltage identification signal.
