Abstract
Described is an apparatus having a non-linear control to manage power supply droop at an output of a voltage regulator. The apparatus comprises: 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 couple 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.
