Abstract
A switching power supply which takes out an output current from a secondary winding when a switching circuit for switching a current flowing through a primary winding is turned off and supplies a DC output to a load device having a control input for decreasing an amount of consumption power thereof. The switching power supply includes a voltage reduction detection circuit for detecting a voltage generated at the secondary winding when the switching circuit is in an on-state and for outputting to the control input a reduction signal representing reduction of an input voltage of the primary winding side when the detected voltage is out of a predetermined range.
