Claim 6:
7. A controller for a multi-output AC/DC converter, the converter comprising a main power stage and a plurality of chopper stages, each chopper stage corresponding to one of the multiple outputs of the multi-output AC/DC converter, wherein the controller comprises:
first circuitry configured to negotiate a power delivery contract with one or more devices coupled to the multiple outputs of the multi-output AC/DC converter;
second circuitry that determines a highest voltage from the negotiated power delivery contracts;
third circuitry that provides a reference voltage corresponding to the highest voltage from the negotiated power delivery contracts to a feedback circuit of the main power stage; and
fourth circuitry that provides a feedback voltage to the feedback circuit of the main power stage, the feedback voltage being an output of the chopper stage corresponding to the highest voltage from the negotiated power delivery contracts.
