A power supply module includes an inductor circuit, a switch circuit, a sensor circuit, and a controller. The inductor circuit includes an inductor and a voltage feedback wire returning the terminal voltage of the inductor. The switch circuit is electrically connected to the inductor circuit for driving the inductor circuit. The sensor circuit is electrically connected to the switch circuit and the voltage feedback wire, in which the sensor circuit controls the switch circuit and generates a current feedback signal according to the terminal voltage of the inductor. The controller is electrically connected to the sensor circuit, in which the controller controls the sensor circuit according to the current feedback signal.
