Abstract
There is provided a configuration of a switching control circuit for use with a switching power supply which generates an output voltage from an input voltage, the switching control circuit having an intermittent operation mode where an operation period in which a switching element of the switching power supply is switched and a pause period in which the switching element is not switched are repeated. The switching control circuit includes a prohibition part configured to prohibit starting a next operation period until a predetermined period of time elapses from a time that a current operation period starts, in the intermittent operation mode.
