[Outline]
This IC is LED Lighting power supply IC is corresponding to the TRIAC dimming, PWM dimming and DC dimming. It adopts a quasi resonant switching, and has realized the low loss and low noise. This IC is realized non-linear current curve by combination of peak current control and OFF-time variable control, thereby it to allow visually smooth dimming curve. And equipped with output terminal of phase detector for bleeder current control, it to allow reduce parts.
