Abstract
A control circuit for controlling power switch in switching power supply circuit. The optimization circuit comprises an adaptive amplitude jitter generating circuit, a comparison circuit and a trigger circuit. The adaptive amplitude jitter generating circuit is used to generate a periodic amplitude jitter signal according to the feedback voltage signal indicative of the output of the switching power supply circuit. The comparison circuit is used to compare the sampled voltage signal with periodic amplitude jitter signal, and generate an output signal with periodic fluctuations. The trigger circuit is used for outputting the control signal for driving the power switch according to the output signal with periodic fluctuations and the clock signal.
