A power supply device generating an output voltage and including a first switching module, a second switching module, a detection module, a pulse width modulation (PWM) module and an energy storage filter module is disclosed. The first switching module is coupled between a first voltage source and a switching node. The second switching module is coupled between the switching node and a second voltage source. The detection module detects voltage of the switching node. The PWM module generates a first PWM signal and transmits the first PWM signal to the first switching module according to a detection result of the detection module. The energy storage filter module processes the voltage of the switching node to generate the output voltage.
