15. A power converter, comprising:
a regulating circuit to provide a regulating circuit output voltage in response to an input voltage received by the regulating circuit, wherein the regulating circuit output voltage is regulated in response to a first signal; and
a switched capacitor circuit coupled to the regulating circuit, the switched capacitor circuit being a multiple phase circuit having multiple paths associated with corresponding voltages out of phase with each other, the switched capacitor circuit comprising at least one capacitor and a plurality of switches being switched substantially in accordance with a switching frequency to alternatively charge or discharge the at least one capacitor based, at least in part, on a dead-time interval associated with the switched capacitor circuit;
wherein the switching frequency varies in response to an output current of the power converter.
