Abstract
A power converter includes a network of switches having a first capacitor switch coupled to a first flying-capacitor, a first switch to couple a second flying-capacitor to a first port, an inductor coupled to a ground switch. A driver drives the network of switches in two states. In the first state the ground port is coupled to a second port via a first path comprising the first flying-capacitor and the inductor, and the first port is coupled to the second port via a second path comprising the first switch, the second flying-capacitor and the inductor. In the second state the ground is coupled to the second port via a third path comprising the ground switch and the inductor, and one of the first port and the ground port is coupled to the second port via a fourth path comprising the first flying-capacitor while bypassing the inductor.
