The invention relates to a power supply module which comprises an inductance circuit, a switch circuit, a check driving circuit and a controller, wherein the inductance circuit is provided with an inductor and a voltage feedback line, and the voltage feedback line feeds back the end voltage of the inductor. The switch circuit is electrically connected with the inductance circuit to drive the inductance circuit. The check driving circuit is electrically connected with the switch circuit and the voltage feedback line, and the check driving circuit controls the switch circuit and generates a current feedback signal according to the end voltage of the inductor. The controller is electrically connected with the check driving circuit, and controls the check driving circuit according to the current feedback signal.
