Abstract:
A DC-DC converter is provided. When a load of the DC-DC converter is too light, the DC-DC converter can raise a frequency of its PWM signal, and reduce a pulse width of the PWM signal, so as to avoid the frequency of the PWM signal falling into a frequency range that can heard by human's ear and maintain high conversion efficiency of the DC-DC converter.
