Abstract: A multi-output DC/DC converter, which may be included in an electronic apparatus, performs sync switching control using a simplified configuration. The DC/DC converter may include a first switching unit which alternately switches input DC power and converts the DC power into AC power, a converter which converts the AC power and outputs first power and second power, a first output unit which receives the first power and outputs an output voltage, a second output unit which includes a second switching unit, and receives and switches the second power through the second switching unit and outputs an output voltage, and a controller which detects a voltage applied to a winding wire of the first output unit, generates a sync signal by using the detected voltage, compares the sync signal with a predetermined reference and controls the second switching unit to synchronize the second switching unit with the first switching unit.
