Description

The AL5822 is a 100Hz/120Hz LED current ripple suppressor for LED 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.
