Abstract

A DC-DC converter includes first and second converters. The first converter generates a first power voltage based on a power voltage from an input terminal, and outputs the first power voltage to a first output terminal. The second converter generates a second power voltage based on the input power voltage, and outputs the second power voltage to a second output terminal. The second converter includes a plurality of inverting converters and a controller. The inverting converters generate a check current to check a connection state of an inductor when the inductor is connected. The second power voltage is generated by converting the input power voltage in response to a PWM signal. The controller generates a driving control signal based on the check current to operate a predetermined number of the inverting converters connected to the inductor, and to control the inverting converters based on the driving control signal.
