Abstract: 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 the power supplied from the supply; and a second IC to supply power to a field-effect transistor (FET), wherein, when a preset control command is received through the IR receiver, the first IC turns on the second IC to drive 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.
