ABSTRACT:
In a switching power source, an error signal indicating an error of an output voltage is applied to an insolation element whose input and output are insolated from each other, and an output of the insolation element is utilized to control a switching operation, thereby to stabilize the output voltage. The switching power source includes a power outage detecting section in which, when an input voltage of a switching circuit adapted to switch a current flowing in a primary coil becomes lower than a predetermined value, the level of the error signal is a limit level, and when the level of the error signal becomes the limit level, a power outage detection signal is produced.
