A switching regulator converts an AC input voltage into an output voltage, to power a load. The switching regulator includes a power stage having a main power switch. The main power switch has different ON time durations under different AC input voltage conditions and different load currents.

Switching regulator with THD and PF compensation, the control circuit and the method thereof

A switching mode power supply preventing false triggering of an over current protection due to a surge pulse. The switching mode power supply has a switch and an inductor. An inductor current flows through the inductor. The switching mode power supply turns off the switch and meanwhile starts timing for a preset period of time when the inductor current is larger than a preset value. The switch is kept off during the preset period of time and is then turned on when the preset period of time expires.
