Abstract
A power converter includes a first flying capacitor, an inductor, and a driver. A network of switches has a first switch to couple the first flying capacitor to a first port, and a second switch to couple the inductor to ground. The driver is adapted to drive the network of switches with a sequence of states that includes a first state and a second state. 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 decoupled from the second port. In the second state the ground port is coupled to second port via a second path comprising the second switch and the inductor, and the first port is coupled to the second port via a third path comprising the first flying capacitor while bypassing the inductor.
