1. An apparatus comprising:

  • a first inductor for coupling to a load;

    a capacitor, coupled to the first inductor, and for coupling to the load;

    a first high-side switch coupled to the first inductor;

    a first low-side switch coupled to the first inductor;

    a bridge controller to control when to turn on and off the first high-side and first low-side switches; and

    a non-linear control (NLC) unit to monitor output voltage on the load, and to cause the bridge controller to turn on the first high-side switch and turn off the first low-side switch when a voltage droop is detected on the load.
