ABSTRACT:
One embodiment of the invention includes a system for regulating an output voltage of a power converter. The system comprises an error amplifier that compares a feedback voltage associated with the output voltage with a reference voltage to generate an error signal that is employed to control a magnitude of the output voltage. The system also comprises a plurality of sample and hold circuits each configured to sample an error amplifier output voltage to provide the error signal. The system further comprises a switching controller configured to control switching of the error amplifier output voltage between each of the plurality of sample and hold circuits in response to a change in an output load of the power converter.
