lighting applications. Combined with a pre-stage APFC LED driver, the AL5822 circuitry can efficiently suppress the low frequency (100Hz/120Hz) LED current ripple from the APFC output, thus eliminate the low frequency flickering for various LED lamps. VIN 1 6 VLMT The AL5822 adopts high efficiency driving mechanism. It can automatically adapt to different LED chains’ voltage and current, to GND 2 5 VS
T
