摘要
A switched-capacitor DC-DC power converter circuit is provided. The switched-capacitor DC-DC power converter circuit includes N input-side switched capacitor units and N output-side switched capacitor units. There is a charge recycling phase located between two adjacent conversion phases. In the 2N conversion phases, a bottom end of a capacitor of at least one of the input-side switched capacitor units and a bottom end of a capacitor of at least one of N output-side switched capacitor units is selectively electrically connected to an output terminal of the switched-capacitor DC-DC power converter circuit. In each charge recycling phase, bottom ends of two capacitors of N input-side switched capacitor units and N output-side switched capacitor units are electrically connected to each other through two of the input-side charge recycle switches and output-side charge recycle switches.
