Abstract
The present invention provides a short-circuit protecting circuit of a switching regulator which does not require a capacitor having a large capacity in order to obtain a sufficient duty time. A pulse generating circuit for generating one clock with a short-circuit detection signal as a trigger signal is added, and a counter circuit for counting clock pulses of a clock signal is further inserted between a comparator and a latch circuit, whereby it becomes possible to produce a sufficient delay time based on a signal having a short period using a capacitor having a small capacity.
