Cxle86144 is a single channel high voltage linear constant current LED driver chip. It adopts linear constant current technology and sets the driving current of LED light string through external resistance. Cxle86144 has the function of line voltage compensation. When the input voltage is too high, it will automatically reduce the LED lamp string current, ensure that the input power is basically unchanged, and ensure the thermal stability of the system. AC220V high PF scheme, single maximum drive 6W; AC120V high PF or no stroboscopic scheme; thermal resistance 50 ℃, IC pin 80 ℃, IC enters over temperature protection; mains input changes 10V, power linear adjustment rate 1%.
