ABSTRACT:
In a DC-DC converter of this invention, a voltage detection circuit is connected in parallel with an output switching device, and the voltage detection circuit is put into operation a predetermined time after the output switching device is turned on. In addition, a detection switching device, which constitutes the voltage detection circuit, is designed to have a higher ON resistance than an ON resistance of the output switching device.
