Yao-Yi Yang 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).

  • Patent number: 8581562
    Abstract: The present invention relates to a Single Inductor Double Output (SIDO) power converter, which includes a power-stage circuit, a current detector, a slope compensation device, at least two error amplifiers, a comparing unit, a mode exchange circuit, a logical device and a driver. The SIDO current converter achieves an optimal SIDO power converting efficiency by controlling a full-current mode. Furthermore, different power transferring modes, under a variety of loadings, are used to address the issue of cross regulation and at meanwhile solving output voltage ripples and transient response to ensure the SIDO power converter a more flexible usage environment and better output performance.

  • Patent number: 8232743
    Abstract: A voltage converter for use in a backlight module stores energy of an input voltage using an inductor and outputs a plurality of output voltages accordingly. The charging path of the inductor is controlled according to the first output voltage so that the first output voltage can be stabilized. The discharging paths from the inductor to other output voltages are controlled according to the differences between other output voltages and the first output voltage so that other output voltages can also be stabilized.
