Claim 13:
14. A method of operating a power conversion circuit, the method comprising:
providing a circuit comprising first, second, third and fourth capacitors coupled to a plurality of switches;
providing a first output terminal, a second output terminal, an input terminal and a ground coupled to the circuit;
repetitively cycling the circuit between a first state and a second state and generating a first output voltage at the first output terminal and generating a second output voltage at the second output terminal;
when in the first state, coupling the first capacitor in parallel with the second capacitor, and coupling the first and second capacitors between the ground and the first output terminal; and
when in the second state, coupling the first capacitor in series with the second capacitor, and coupling the series connected first and second capacitors between the second output terminal and the ground;
wherein the first output terminal is connected to the input terminal via the third capacitor; and
wherein the second output terminal is connected to ground via the fourth capacitor.
