Abstract
A switching power conversion circuit includes a conversion capacitor, a capacitive power conversion circuit, an inductor, an inductive power conversion circuit and a switching control circuit. The capacitive power conversion circuit includes plural switching devices for generating an intermediate voltage which is in a predetermined proportional relationship to the input voltage. The inductive power conversion circuit includes plural switching devices for converting the intermediate voltage to an output voltage. The plural switching devices of the capacitive power conversion circuit and the inductive power conversion circuit switch the conversion capacitor and the inductor periodically according to the duty ratio of the switching control signal generated by the switching control circuit. The capacitive power conversion circuit and the inductive power conversion circuit share one of the plural switching devices.
