Abstract: A DC-DC power converter has a ground terminal, an input terminal for receiving an input voltage and an output terminal for providing an output voltage with a target conversion ratio. The power converter includes a coupled inductor having a first winding and a second winding coupled to the output terminal; a first flying capacitor coupled to a first inductor and to the second winding; a second flying capacitor coupled to a second inductor and to the first winding; an input capacitor coupling the input terminal to the ground terminal; an output capacitor coupling the output terminal to the ground terminal; a network of switches; and a driver adapted to drive the network of switches with a sequence of states during a drive period, wherein the sequence of states forms a switching cycle.
