Abstract
A switching control circuit for a power supply circuit including a first coil, a second coil configured to generate a voltage corresponding to a current flowing through the first coil, and a switching device configured to control the current flowing through the first coil. The switching control circuit controls switching of the switching device, and includes: a drive signal generator circuit configured to generate a driving signal, based on a feedback voltage corresponding to the output voltage; a driver circuit configured to switch the switching device, in response to the driving signal; a regulator configured to generate a power supply voltage of a target level to operate the driver circuit, and a drive current of the driver circuit; and a control circuit configured to control the regulator to decrease the drive current in response to the drive current reaching a predetermined value.
