Abstract
The present invention includes a turn-off signal modulating circuit that periodically varies a turn-off timing of a switching elementat a preset modulation time after a current detection by a drain current detecting circuit, and by modulating the peak of a current flowing through the switching element, diffuses switching noise while preventing concentration of an oscillating frequency at a constant frequency even under a constant input voltage and a constant load.
