Abstract
Provided is a switching power supply apparatus that shifts to an OFF mode when electronic equipment is on standby, and includes: an OFF mode delay circuit that delays shifting to the OFF mode; and an electric storage unit and a power supply circuit that function as a power supply source of an OFF mode control circuit. With the configuration, the power consumption can almost be eliminated, and the switching power supply apparatus can start without any charge in an electricity storage component such as a primary battery or a secondary battery.
