Abstract
An example power converter includes a clock signal generator coupled to generate a clock signal to control switching of a power switch to be coupled to the control circuit. Feedback circuitry is coupled to receive a feedback signal, which is representative of an output of a power converter during a feedback portion of an off time of the power switch. The feedback circuitry is coupled to respond to the feedback signal to control the clock signal generator to regulate a duty cycle of the feedback portion of the off time of the power switch as a proportion of a total power switch switching cycle period.
