Abstract
A switching control circuit for controlling switching of first and second transistors of a power supply circuit. The switching control circuit including: a load detection circuit detecting a state of a load; a drive signal output circuit outputting a drive signal that causes the power supply circuit to operate in a burst mode and a normal mode respectively when the load is light and heavy loads. The drive signal output circuit operates in a first state in which the drive signal is outputted based on a predetermined condition, a second state in which the drive signal is outputted to gradually reduce an ON period of the first and second transistors and a third state in which outputting of the drive signal is stopped, and enters the third state from the first state without going through the second state immediately after the power supply circuit starts operating in the burst mode.
