Línea de modelo para esta hoja de datos Versión de texto del documento AL5822 ADAPTIVE 100Hz/120Hz LED CURRENT RIPPLE SUPPRESSOR Description Pin Assignments The AL5822 is a 100Hz/120Hz LED current ripple suppressor for LEDTop View 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 VST eliminate the LED current ripple, meanwhile minimize the powerC consumption on the Power MOSFET. VC 3 4U VG The AL5822 has built-in protections, such as Over-Temperature-D Protection (OTP), Over-Current-Protection (OCP) and LED Short-CircuitO Protection (SCP). R SOT26 P The AL5822 is available in the SOT26 package.
