1. A power conversion apparatus, comprising:
a switched-capacitor circuit configured to receive an input voltage and generate a switched-capacitor output voltage at a first node based on the input voltage such that the switched-capacitor output voltage has a different voltage value than that of the input voltage;
a regulating circuit comprising:
a first switch coupled between the first node and an intermediate node;
a second switch coupled between a second node and the intermediate node;
a third switch coupled between a third node and the intermediate node; and
an inductor coupled between the intermediate node and an output node,
wherein the regulating circuit is configured to:
selectively connect the intermediate node to the switched-capacitor output voltage at the first node via the first switch, the input voltage at the second node via the second switch, or a reference voltage at the third node via the third switch; and
generate a regulating output voltage at the output node based on a voltage at the intermediate node by alternating between two different switching configurations of the first switch, the second switch, and the third switch.
