Abstract
Disclosed herein is a switching power supply circuit that includes a switching circuit having an input node connected to an input power supply terminal and an output node connected to an output power supply terminal through an output switch, a feedback circuit configured to feed back information based on a voltage appearing at a control node to the switching circuit, and an activation circuit configured to turn ON the output switch after an elapse of a predetermined time after a voltage appearing at the control node exceeds a predetermined value. The switching circuit is configured to adjust a level of a voltage appearing at each of the output node and the control node based on the information to a predetermined level. The feedback circuit includes an adjustment mechanism configured to adjust a relation between a voltage appearing at the control node and the information.
