ータ。[Claims for Utility Model Registration] A transformer having a primary winding and a secondary winding, a switch element that turns an input DC voltage on and off to the primary winding, and A switching device comprising a rectifying and smoothing circuit that rectifies and smoothes the obtained AC voltage, and a digital control circuit that controls turning on and off of the switch element so that the DC output voltage obtained from the rectifying and smoothing circuit becomes a predetermined voltage. In the regulator, the digital control circuit includes a latch circuit that latches a data signal related to the cycle of turning on and off the switch element at regular intervals, and a latch circuit that integrates the clock and integrates the clock when the integrated value reaches a predetermined value. A counter that resets the value and resets the latch circuit, compares the output of the latch circuit with the integrated value of the counter, and turns on the switch element.
1. A switching regulator, comprising comparison means for outputting a drive signal for turning off.
