Abstract
A power converter is provided. The power converter includes a switched-capacitor conversion circuit and an inductor buck circuit. The switched-capacitor conversion circuit receives an input voltage at an input terminal and performs a switching operation to convert the input voltage to an intermediate voltage. The inductor buck circuit is coupled to an output terminal of the switched-capacitor conversion circuit to receive the intermediate voltage and operates at a constant on-time to generate an output voltage at a conversion output terminal according to the intermediate voltage. The inductor buck circuit includes an inductor. In response to that a state of an inductor current used for charging the inductor corresponds to a predetermined condition, a switching action of the switching operation is enabled, so that the switched-capacitor conversion circuit is switched from a first turned-on state to a second turned-on state.
