Abstract
A power converter and method are presented. The converter provides a ground terminal, an input terminal and an output terminal. The power converter includes first, second and third flying capacitor coupled to a network of switches and a driver. The network of switches has a first switch coupled to the input terminal; a second switch to couple the first flying capacitor to the third flying capacitor; and a third switch to couple the second flying capacitor to the third flying capacitor; The driver is adapted 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 the ground terminal is coupled to the output terminal via a first path with the first flying capacitor and the third flying capacitor, and via a second path with the second flying capacitor.
