Stephanie CANNENTERRE 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).

  • Quasi-resonant valley lockout without feedback reference
    Patent number: 10355606
    Abstract: A method of controlling a power supply includes detecting a transition of the power supply to discontinuous conduction mode (DCM), and locking an operating point of the power supply after detecting the transition. The operating point can be unlocked when a timer expires or when a feedback voltage slope exceeds a threshold.

  • Indicator using existing power supply controller terminals
    Patent number: 10243354
    Abstract: A power conversion circuit has a controller with an input terminal and a circuit configured to drive an electric current out of the input terminal in response to a condition of the controller. An indicator is coupled to the input terminal of the controller. The controller includes a clock signal controlling the electric current out of the input terminal. The input terminal is a voltage sensing terminal or feedback input terminal in some embodiments.

  • Bi-directional feedback pin
    Patent number: 10164540
    Abstract: A controller for a power conversion circuit has a first current-reading circuit coupled for receiving a first feedback signal at a first circuit node and generating an internal feedback signal at a second circuit node inversely proportional to the first feedback signal. A second current-reading circuit is coupled for receiving a second feedback signal at the first circuit node and generating the internal feedback signal at the second circuit node inversely proportional to the second feedback signal. The first current-reading circuit generates the internal feedback signal inversely proportional to an electric current injected into the controller at the first circuit node. The second current-reading circuit generates the internal feedback signal inversely proportional to an electric current drawn from the controller at the first circuit node.
