An input stage circuit of a three-level DC/DC converter is provided. The input stage circuit uses metal-oxide-semiconductor field effect transistors (MOSFETs) to discharge a flying capacitor to maintain the voltage across the flying capacitor at a half of the input voltage. Not only can the input stage circuit solve the high voltage issue across the flying capacitor in the prior art, but the circuit is able to operate normally without increasing power consumption during discharging, thereby avoiding problems of the prior art.
