Classification: CPC G  H  Y | IPC H

Claim 0:
1. A power converter, comprising:
a voltage converting circuit, wherein at least an output voltage of the voltage converting circuit is regulated in response to a first signal; and
a switched capacitor circuit coupled to the voltage converting circuit, the switched capacitor circuit comprising at least one capacitor and a plurality of switches being switched substantially in accordance with a switching frequency;
wherein the switched capacitor circuit is a multiple phase circuit comprising a first switched capacitor element associated with a first phase voltage and a second switched capacitor element associated with a second phase voltage out of phase with the first phase voltage, and each of the first switched capacitor element and the second switched capacitor element changes between a first network state and a second network state in response to one or more second signals to alternatively charge or discharge the at least one capacitor;
wherein the first switched capacitor element and the second switched capacitor element provide an output voltage of the switched capacitor circuit to a node in both the first network state and the second network state, and the switched capacitor circuit and the voltage converting circuit are synchronized based, at least in part, on a dead-time interval associated with the switched capacitor circuit.
