Abstract

A switching regulator circuit includes a gate driver circuit driving a first switch and a second switch to generate a first voltage at a first node. Further, the switching regulator includes an LC filter circuit responsive to the first voltage to generate a desired output voltage. Moreover, the switching regulator includes a regulator circuit coupled to the LC filter circuit to control the gate driver circuit. The regulator circuit accurately controls variations in trip point. The trip point is a voltage at which the second switch is switched OFF by the gate control circuit. The regulator circuit includes one of a Delay Locked Loop (DLL) and a Pulse width modulator (PWM) controller.
