Abstract
A controller includes a first control circuit coupled to an input side of a power converter. The first control circuit includes a timing and delay circuit and a switch selection circuit. A second control circuit is coupled to an output side of the power converter. The second control circuit includes a valley detection circuit and a synchronous rectifier control circuit. A third control circuit is coupled to the input side of the power converter. The third control circuit is coupled to drive an auxiliary switch coupled to an input side of an energy transfer element. The first control circuit is coupled to alternately drive a main switch, which is coupled to the input side of the energy transfer element, and the auxiliary switch in response to a command signal to transfer energy from the input side to the output side of the energy transfer element to drive a load.
