An NMOS switch driving circuit and a power supply device are provided. The NMOS switch driving circuit includes a power-supply unit, a switch unit, a power conversion unit, and a driving unit. The power-supply unit is configured to output a first voltage. The switch unit is electrically coupled between the power-supply unit and a first interface and configured to establish or disconnect an electrical coupling between the power-supply unit and the first interface. The power conversion unit includes a port coupled to the power-supply unit and another port electrically coupled to the switch unit via the driving unit. The power conversion unit is configured to convert the first voltage into a constant driving voltage and output the driving voltage to the switch unit via the driving unit to drive the switch unit to be switched on, to establish the electrical coupling between the power-supply unit and the first interface.
