Ching-Tsao Chen 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).

  • Switched capacitor voltage converting device and switched capacitor voltage converting method
    Patent number: 9350235
    Abstract: A voltage converting device includes first to third voltage converters, each including a capacitor, a pair of charge switches for charging the capacitor, a pair of first output switches for outputting a first output voltage through the capacitor, and a pair of second output switches for outputting a second output voltage through the capacitor. Via timing control of the switches, outputs of the first and second output voltages are substantially continuous and are prevented from floating.
    Type: Grant
    Filed: April 30, 2014
    Date of Patent: May 24, 2016
    Assignee: ILI TECHNOLOGY CORPORATION
    Inventors: Wei-Chung Cheng, Ching-Tsao Chen, Chih-Hsiang Chuang
