A power converter controller is disclosed. An example power converter controller includes a feedback sensor circuit coupled to receive a feedback signal representative of an output of the power converter. The controller also includes a feedback sampling signal generator coupled to generate a feedback sampling signal coupled to be received by the feedback sensor circuit. The feedback sensor circuit is coupled to sample the feedback signal in response to the feedback sampling signal. The controller also includes a state machine coupled to the feedback sensor circuit to control switching of a switch of the power converter circuit according to one of a plurality of operating condition states in response to the feedback sensor circuit. The controller also includes a feedback time period signal generator coupled to generate a feedback time period signal coupled to be received by the state machine. A period of a feedback time period signal is substantially greater than a period of the feedback sampling signal. The state machine is coupled to be updated in response to the feedback time period signal.
