Abstract
Provided is a DC-DC converter including a short-circuit protection circuit which can stably perform a reset operation and a stop operation. The short-circuit protection circuit includes a detection circuit, a delay circuit, and a latch circuit. The delay circuit is reset in response to an output voltage abnormality signal related to a switching regulator which is outputted from the latch circuit. The latch circuit is reset based on an AND operation between the output voltage abnormality signal and a UVLO signal.
