Claim 19:
20. A controller for use in a power converter having a plurality of outputs, comprising:
a multi-output control block coupled to control switching of at least one pulse transfer switch coupled to one of the plurality of outputs, wherein the multi-output control block is configured to generate a request for an energy pulse for one of the plurality of outputs, wherein the request for the energy pulse is transferred to a primary switching control block and wherein the primary switching control block is coupled to control switching of a primary switch coupled to an input of the power converter to transfer the requested energy pulse from the input to one of the plurality of outputs, the multi-output control block comprising:
a multi-output signal process block coupled to receive a plurality of feedback signals from the plurality of outputs and to output the request for the energy pulse in response to at least one of the plurality of feedback signals dropping below a threshold reference, wherein the multi-output signal process block is coupled to turn ON the pulse transfer switch to transfer the requested energy pulse to the one of the plurality of outputs with the one of the plurality of feedback signals which dropped below the threshold reference.
