Abstract
Provided is a DC/DC converter capable of immediately resuming to a normal operation from a state in which an output transistor is continued to be turned off when a reverse current is generated in a light load state. The DC/DC converter includes an ON-timer circuit including: a ripple generation circuit; a smoothing circuit; a timer circuit configured to output an ON-time signal; a logic circuit configured to detect a sign of generation of a reverse current; and a switch circuit configured to, based on a detection signal of the logic circuit, maintain an output voltage of the ripple generation circuit or control the output voltage of the ripple generation circuit to a predetermined voltage.
