1. An apparatus comprising:

  • a first switch coupled to an input node;

    a second switch coupled to the first switch and to an output node;

    a power supply port connected to the input node;

    a charger having a first charge port, and a second charge port to couple the charger to the first switch and the second switch; and

    a control circuit coupled to the first switch, the second switch, and the output node, the control circuit to activate the second switch when a system voltage detected at the output node is less than a threshold voltage, and to control the second switch to maintain the system voltage at the threshold voltage when the system voltage exceeds the threshold voltage,wherein the control circuit includes a resistance divider and an error amplifier.
