Abstract: A method for controlling a boost converter which generates an output voltage according to an input voltage. The boost converter includes an inductor, a first transistor, a second transistor, and a capacitor. The first transistor is coupled between the inductor and a ground. The second transistor is coupled between the inductor and an output terminal. The capacitor is coupled to both the second transistor and the output terminal. The method includes: charging the capacitor by repeatedly turning on the second transistor within a first time interval; turning on the first transistor and the second transistor by turns according to a first switching frequency within a second time interval; and turning on the first transistor and the second transistor by turns according to a second switching frequency within a third time interval. The first switching frequency is smaller than the second switching frequency.
