COMBINED INDUCTIVE AND SWITCHED CAPACITIVE POWER SUPPLY CONVERSION

摘要

A DC-DC switching converter with an LC output filter has a switched capacitor converter providing the capacitance of the output filter. The switched capacitor converter may be a multi-phase switched capacitor converter. Topology of connections between capacitors of the multi-phase switched capacitor converter may be dependent on phases of clock signal(s) provided to the multi-phase switched capacitor converter. The switched capacitor converter may rely on parasitic inductances, or include discrete inductors, in series between connected capacitors to allow for adiabatic or near adiabatic voltage conversion.
