Abstract
A power supply device includes a voltage converting circuit and a mode switching circuit. The voltage converting circuit is configured to receive a first voltage and convert the first voltage to a second voltage. The mode switching circuit is configured to provide an output voltage and an output current to a load according to the second voltage. The mode switching circuit includes a switch configured to maintain on or off on the condition that the power supply device is operated under a constant voltage output mode such that the value of the output voltage corresponds to the second voltage, and the switch is configured to switch between on and off on the condition that the power supply device is operated under a constant current output mode such that the output current of the mode switching circuit is a constant value.
