  • DC power converting circuit and method thereof
    Patent number: 8502512
    Abstract: A direct current (DC) converting circuit includes a DC input end, for receiving a DC input voltage; a DC output end, for providing a predetermined DC voltage; a switch, coupled between the DC input end and the DC output end, for providing a direct path; a DC-DC step-down unit, coupled between the DC input end and the DC output end, for providing a step-down voltage path; and a control unit, coupled to the switch and the DC-DC step-down unit, for detecting the DC input voltage and selecting either the direct path or the step-down voltage path to provide the predetermined DC voltage at the DC output end. The DC power converting circuit can be applied in power supply circuits of multi-media players or TV setup boxes to convert DC input voltage including 5V, 9V or 12V DC voltages to a predetermined DC voltage.
