Cxle86184 is a segmented linear constant current LED driver chip. With segmented linear architecture, it can automatically switch LED light strings according to segmented led voltage drop

Cxle86184 is a segmented linear constant current LED driver chip. With segmented linear architecture, it can automatically switch LED light strings according to segmented led voltage drop without external settings, simplifying the system design. No electrolytic capacitor, inductor or transformer is needed in the periphery of the system. The whole system is simple and low cost. Cxle86184 can drive up to three series LED lamp strings. When the input voltage changes, the number of connected led strings will be changed automatically. In the whole AC cycle, the time for led to be lit is increased, so the utilization rate of LED is improved and the power factor is improved. The PFC is as high as 0.99, and the thd is less than 15%. Cxle86184 uses constant current control and compensation technology, and the current accuracy can be controlled within ?3%. In addition, the current of each LED string can be set flexibly through different sampling resistance values
