摘要
The present invention provides a DC-DC converter, wherein the DC-DC converter includes a controller, a first switch, a second switch, an inductor and a ripple signal generator. The controller is configured to generate an up signal and a down signal according to an output signal and a ripple signal. The first switch is coupled between an input voltage and a first node, and is controlled by the up signal. The second switch is coupled between the first node and a reference voltage, and is controlled by the down signal. The inductor is coupled between the first node and an output node, and is configured to receive a first signal from the first node to generate the output signal at the output node. The ripple signal generator is configured to generate the ripple signal, and reset the ripple signal every cycle to a specific voltage.
