Claim 0:
1. A control system for use in a power converter having a plurality of outputs, comprising:
a primary switching control block coupled to control switching of a primary switch coupled to an input of the power converter, wherein the primary switching control block is coupled to control switching of the primary switch to transfer energy pulses from the input of the power converter to the plurality of outputs of the power converter through a single magnetic component;
a secondary control block coupled to control switching of a synchronous rectifier (SR) switch coupled to a common return line of the plurality of outputs, wherein the secondary control block is coupled to synchronize switching of the SR switch with the turn off of the primary switch; and
a multi-output control block coupled to control switching of at least one pulse transfer switch that is coupled to one of the plurality of outputs to regulate the plurality of outputs, wherein a request for an energy pulse from one of the plurality of outputs is transferred to the primary switching control block to turn ON the primary switch to transfer the requested energy pulse, wherein the multi-output control block is further coupled to turn ON a respective pulse transfer switch corresponding to the request for the energy pulse from one of the plurality of outputs, the multi-output control block comprising:
an interface coupled to communicate with the secondary control block to send the request for the energy pulse to the secondary control block and to receive an acknowledge signal from the secondary control block, wherein the acknowledge signal represents a confirmation of receipt of the request for the energy pulse.
