Circuit and method for improved battery life during suspend mode

Abstract:

Circuit and method for reducing use of battery power during suspend mode operation of a computing device. Output impedance circuitry coupled to voltage regulation circuitry produces a feedback voltage and converts an output signal, produced in response to an input voltage and the feedback voltage, to an output voltage. A portion of the impedance of the output impedance circuitry is altered by control circuitry in response to a control signal, thereby causing changes in the feedback voltage, the output signal and the output voltage.
