Abstract
A power supply device may include: a standby power unit converting a direct current (DC) voltage to an operating voltage and a first standby voltage and providing the first standby voltage to a standby output terminal; a DC/DC converting unit receiving the operating voltage from the standby power unit, converting the DC voltage to a main voltage, and providing the main voltage to a main output terminal; and a main/standby power unit converting the main voltage from the DC/DC converting unit to a second standby voltage and providing the second standby voltage to the standby output terminal. The standby power unit varies a magnitude of the first standby voltage based on whether or not the second standby voltage is supplied to the standby output terminal.
