  • 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.
