Patent ID: 7432687

Claim:
A switching power supply comprising: at least one power signal input structured as circuitry for providing an input electrical power signal to the switching power supply; at least one power signal output structured as circuitry for providing an output electrical power signal from the switching power supply; a passive component set comprising at least one passive component; an active component set comprising at least one power supply switch, said at least one power supply switch having a gate and a drain, with the active component set being electrically interconnected to the passive component set so that a switch position of the at least one power supply switch at least partially controls the flow of electrical power through the passive component set; driver/controller circuitry structured to control at least the opening and closing of the at least one switch of the active component set, with the driver/controller circuitry, the active component set and the passive component set being structured, programmed and/or electrically interconnected to convert the input electrical power signal into a desired output electrical power signal; wherein the driver/controller circuitry comprises gate reference voltage generator circuitry structured and electrically interconnected to apply a gate reference voltage to the gate, with the gate reference voltage being offset from a drain voltage in an amount reasonable to compensate for gate capacitance effect on the gate voltage; and wherein the switching power supply has an electrical power efficiency generally greater than 95% at operating voltages.
