Abstract:
A voltage regulator controller is disclosed including: a reference voltage generator for generating a reference voltage; a comparison circuit, coupled with the reference voltage generator, for comparing the reference voltage with an output voltage of a voltage regulator; and a control circuit, coupled with the reference voltage generator and the comparison circuit, for controlling the reference voltage generator to stepwise lower the reference voltage when a power saving command is received by the voltage regulator controller.
