Abstract: A DC-DC converter adopted in a mobile device, for converting a DC input voltage to a DC output voltage is provided. The converter comprises an input circuit, a control circuit, and a switch. The input circuit is connected in series with a line for supplying the DC input voltage and includes a parallel connection of a first capacitor and a snubber circuit. The control circuit is provided for producing a control signal. The switch, connected with the input circuit, is adapted to turn ON or OFF in accordance with the control signal, so as to produce the DC output voltage.
