Claim:
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; a non-linear control (NLC) unit having an input coupled between the first inductor and the load to monitor an output voltage on the load, and an output to provide a trigger signal to cause the bridge controller to turn on the first high-side switch and turn off the first low-side switch when a droop on the output voltage is detected on the load, wherein the trigger signal is a pulse signal having a pulse width indicative of a time duration of the output voltage droop, wherein the NLC unit comprises: a second comparator; and a network of devices forming a high pass filter to couple Alternating Current (AC) output voltage on the load to input of the second comparator, wherein an output of the second comparator to control a second logic unit.
