Abstract: A switched-capacitor power stage includes a first sub-power stage. The first sub-power stage includes a first inductor, a first high switch, a first low switch, and a first set of switched-capacitor networks. The first inductor is coupled to an input terminal. The first high switch is coupled between the first inductor and an output terminal. The first low switch is coupled between the first inductor and a first transition node. The first set of switched-capacitor networks is coupled between the first transition node and the output terminal.
