AL5822中文资料Adaptive 100/120Hz LED Current Ripple Suppressor数据手册Diodes规格书

描述 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.The AL5822 adopts high efficiency driving mechanism. It can automatically adapt to different LED chains’ voltage and current, to eliminate the LED current ripple, meanwhile minimize the power consumption on the Power MOSFET.The AL5822 has built-in protections, such as Over-Temperature- Protection (OTP), Over-Current-Protection (OCP) and LED Short-Circuit Protection (SCP).The AL5822 is available in the SOT26 package.
