The present invention relates to a power supply device comprising: a standby stage for converting direct voltage into predetermined sized operating voltage and a first standby voltage and providing the first standby voltage to a standby output terminal; a DC/DC stage for receiving the operating voltage of the standby stage, converting the direct voltage into a predetermined sized main voltage and providing the main voltage to a main output terminal; and a main/standby stage for converting the main voltage in the DC/DC stage into a predetermined second standby voltage and providing the second standby voltage to the standby output terminal. The standby stage converts the first standby voltage based on whether the second standby voltage is provided to the standby output terminal. |
