摘要： A flyback DC-DC converter is disclosed herein. The flyback DC-DC converter includes a transformer, a voltage divider and a controller. The transformer receives a DC input voltage and converts the DC input voltage to a DC output voltage. The voltage divider is coupled to a first secondary winding of the transformer, and generates a feedback signal indicative of the DC output voltage. The controller is coupled to the transformer via an input switching circuit and controls the input switching circuit to regulate the DC output voltage according to the feedback signal. A skip operation is triggered if the voltage of the feedback signal is higher than a preset reference voltage at the end of a turn-off period of the input switching circuit, and the voltage of the feedback signal is changed to zero during the skip operation.
