Abstract

See full text

A power converter and a corresponding method of converting power are presented. The power converter includes a ground port, an input port for receiving an input voltage and an output port for providing an output voltage; an inductor; a flying capacitor; a network of switches; and a driver to drive the network of switches with a sequence of states during a drive period. The sequence of states includes a first state and a second state. In the first state one of the input port and the output port is coupled to the ground port via a first path comprising the inductor. In the second state the remaining state among the input port and the output port is coupled to the ground port via a second path and a third path, the second path comprising the flying capacitor and bypassing the inductor, and the third path comprising the inductor.
