Abstract
A DC-DC converter includes: a transformer including primary and secondary windings; a switching element that drives the primary winding; a comparator that compares a voltage induced in the secondary winding with a predetermined voltage to detect that the voltage is outside a predetermined voltage range; and a controller. The controller stops switching operation of the switching element when the voltage is outside the predetermined voltage range. Preferably, the DC-DC converter is of a flyback system.
