Patent ID: 7859131

Claim:
A system for regulating an output voltage of a power converter, the system comprising: a single power converter coupled to and providing power at the output voltage to a plurality of output loads; 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; a plurality of sample and hold circuits each configured to sample an error amplifier output voltage to provide the error signal from a different one of the output loads; and 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, wherein the switching controller is further configured to control switching of the output voltage between each of the plurality of output loads concurrently with the switching of the error amplifier output voltage between each of the plurality of sample and hold circuits that corresponds to the respective output load.
