POWER CONVERTER INTEGRATED CIRCUIT

A power converter integrated circuit comprising: a switch network having coupling nodes for coupling the switch network to: a first capacitor; a second capacitor, a third capacitor; and an inductor, wherein the power converter integrated circuit is operable in a first forward mode as switched capacitor power converter circuitry and in a second forward mode as inductive converter circuitry, wherein: in the first forward mode, the switch network is operative to: couple the first and second capacitors in series in a first phase of operation; and couple the second capacitor and the third capacitor in parallel in a second phase of operation; and in the second forward mode, the switch network is operative to: couple the first and second capacitors in series and couple a series combination of the inductor and the third capacitor in parallel with the second capacitor in a phase of operation; and couple the first and second capacitors in parallel with the series combination of the inductor and the third capacitor in a subsequent phase of operation.
