  • Power delivery to a driver circuit in a postregulator
    Patent number: 11804775
    Abstract: In some examples, a device includes a selector circuit configured to deliver power to a first driver circuit, where the first driver circuit is configured to activate and deactivate a first switch of a postregulator. The device also includes a startup regulator and a controller configured to cause the selector circuit to deliver power from the startup regulator to the first driver circuit. The controller is also configured to determine that a boost regulator is operational after delivering power from the startup regulator to the first driver circuit. The controller is further configured to cause the selector circuit to deliver power from the boost regulator to the first driver circuit in response to determining that the boost regulator is operational.

  • Circuit for controlling an output of a power converter
    Patent number: 11682962
    Abstract: This disclosure includes systems, methods, and techniques for controlling a semiconductor device of a power converter. For example, a circuit includes first control circuitry configured to receive an indication of a first voltage which represents a voltage output from a power source to the power converter. Additionally, the first control circuitry is configured to output a control signal to second control circuitry in order to control, based on the first voltage and the second voltage, the semiconductor device so that a second voltage is lower than the first voltage, wherein the second voltage represents a voltage output from the power converter to a load.
