A multi-level power converter and a method using first, second, third and fourth switching elements, an inductor, and a flying capacitor are presented. A first terminal of the inductor may be connected to a switching terminal connecting the second and third switching elements. A first terminal of the flying capacitor may be connected to a terminal connecting the first and second elements. A second terminal of the flying capacitor may be connected to a terminal connecting the third and fourth switching elements. The multi-level power converter may have a first feedback circuit to generate control signals for setting the switching elements in a plurality of switching states for regulating an output voltage or an output current. The converter may have a second feedback circuit to generate control signals to allow the flying capacitor to be charged or discharged using an inductor current flowing through the inductor.
