  • Configurable charge controller
    Patent number: 10185342
    Abstract: A configurable charge converter may include an adaptive low-dropout regulator. The adaptive low-dropout regulator may include a headroom detection circuit and a power supply controller. The headroom detection circuit may monitor a voltage drop across a field effect transistor (FET) and cause a programmable power supply to increase or decrease an output voltage accordingly. In some aspects, the configurable charge converter may include an adaptive low-dropout regulator and a buck/boost converter. The output power of the configurable charge controller may be provided by the adaptive low-dropout regulator, the buck/boost converter, or by both the adaptive low-dropout regulator and the buck/boost converter operating in combination.
