Patents by Inventor Daiwen Sun

Daiwen Sun 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).

  • Voltage regulator circuitry
    Patent number: 11169554
    Abstract: The present disclosure relates to voltage regulator circuitry comprising an input for receiving a supply voltage, an output for outputting an output voltage, and control circuitry configured to receive a reference voltage. The voltage regulator circuitry is selectively operable in either a closed-loop mode in which the control circuitry receives a voltage indicative of the output voltage such that the voltage regulator circuitry regulates the output voltage based on the voltage indicative of the output voltage and the reference voltage received by the control circuitry or an open-loop mode in which the control circuitry does not receive the voltage indicative of the output voltage and the voltage regulator circuitry regulates the output voltage based on the reference voltage received by the control circuitry.
