Abstract: In described example, a circuit includes an error amplifier that receives a reference voltage and an output voltage, and generates an error signal. A comparator receives the error signal and a feedback signal, and generates a primary signal. A logic circuit is coupled to an output terminal of the comparator, and receives a clocking pulse. A clocking circuit is coupled to one of a first and a second output terminal of the logic circuit. The clocking circuit receives a clock signal and generates the clocking pulse. A driver circuit is coupled to the logic circuit. A switching circuit, coupled to the driver circuit, receives an input voltage and generates a switching voltage at a switching node. The switching circuit having a first switch coupled to a second switch at the switching node.
