Patents by Inventor Donald Mike McGinnis

Donald Mike McGinnis has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Dual-output direct current voltage converter
    Patent number: 6756772
    Abstract: A step-down switching voltage regulator with a push-pull output stage is adapted to provide a voltage converter with an auxiliary voltage rail that supplies an auxiliary voltage that is higher than the input supply voltage. The push-pull output stage of the step-down voltage regulator is used to drive a charge pump voltage-doubler circuit. In this way, a single integrated topology provides a regulated low voltage output as well as an auxiliary high voltage output. The circuit topology enables a low component count resulting in lower component cost and smaller physical size.
