Abstract
An output voltage detecting circuit is added to a step-down DC-DC converter or a step-up DC-DC converter and is controlled so that an abnormally high increase in a regulated output voltage of the DC-DC converter is detected and the output voltage is inhibited from increasing further so that it may be rapidly returned to a normal value within the range of regulated voltages of the DC-DC converter.
