Abstract |
A DC-DC buck converter includes a buck conversion circuit, a PWM control circuit and a light-load control circuit. A switching circuit in the buck conversion circuit includes multiple upper switching elements and lower switching elements. The PWM control circuit is coupled to the buck conversion circuit and output a control signal to control the upper and lower switching elements. The light-load control circuit, coupled to the PWM control circuit and the buck conversion circuit for receiving an output voltage, the control signal and a light-load threshold value. The light-load control circuit is provided to determine whether the DC-DC buck converter is in a light load state and turn off at least one of the upper switching elements and at least one of the lower switching elements in the light load state.
