1. An electronic device comprising:
a power supply to supply power;
an infrared rays (IR) receiver;
a first integrated circuit (IC) to drive the IR receiver based on power supplied from the power supply; and
a second IC to supply power to a field effect transistor (FET),
wherein, based on a preset control command being received through the IR receiver, the first IC drives the FET, which is connected to the second IC and is in a stopped state while the second IC is in a turned-off state, by turning on the second IC to thereby supply power to the electronic device,
wherein the power supply is configured to:
supply power to the first IC through a first output terminal, and
supply power to the electronic device through a second output terminal connected to the first output terminal through a relay.
