Abstract
A multiple-output integrated power factor correction system includes, for example, a processor that is formed in a substrate and is arranged to monitor each voltage output of two or more output stages of a power supply and in response to generate an individual voltage error signal for each monitored output stage. A combined output voltage error signal is generated in response to each of the individual voltage error signals. The voltage input to the power supply and the total inductor current of the power supply are monitored and used to generate a combined output voltage control signal in response to the monitored input voltage total inductor current as well as the combined output voltage error control signal. Each individual output voltage control signal for each monitored output stage is generated in response to each of the respective generated individual voltage error signals.
