Claim 0:
1. A power converter comprising:
a switched-capacitor conversion circuit receiving an input voltage at an input terminal and performing a switching operation to convert the input voltage into an intermediate voltage; and
an inductor buck circuit coupled to an output terminal of the switched-capacitor conversion circuit to receive the intermediate voltage and operating under a constant on-time to generate an output voltage at a conversion output terminal according to the intermediate voltage,
wherein the inductor buck circuit comprises an inductor, and
wherein 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.
