Abstract
A power supply includes an operating power circuit outputting an operating voltage, a standby power circuit outputting a standby voltage, a starting switching circuit having a first remote control receiver for receiving a first remote control signal and supplying a starting power to the standby power circuit in response to the first remote control signal, a controller having a second remote control receiver for receiving a second remote control signal and performing a function corresponding to the second remote control signal, and a feedback circuit processing a control signal to switch the starting switching circuit to either of a standby mode and a power saving mode in response to a power off signal from either of the second remote control receiver and a power switch.
