Patent ID: 7345463

Claim:
A load compensated voltage regulator, comprising: a chip including a control section comprising an error amplifier, a pulse width modulator (PWM), an input of said PWM hooked to an output of said error amplifier, said PWM outputting at least one driver control signal, at least one driver having an input coupled to receive said driver control signal, and an output stage comprising at least one output transistor having an input coupled to an output of said driver, said output transistor driving an inductor in series with a grounded capacitor, wherein an output of said regulator (V OUT ) is at a node between said inductor and said capacitor, said V OUT generating a load current across a load when connected across said capacitor; a feedback connector for feeding back a feedback signal representative of said load current to circuitry for outputting a gate driver voltage supply control signal based on at least one reference level and said feedback signal, and a connector coupling at least one power supply to said driver through a switch or a second regulator, said gate driver voltage supply control signal being coupled to said switch or regulator, wherein said gate driver voltage supply control signal modulates a voltage level of said power supply between at least two different voltage levels based on said load current.
