The cxle86155 adopts the segmented linear constant current technology, which can set the driving current of the LED light string through the external pin

The cxle86155 adopts the segmented linear constant current technology, which can set the driving current of the LED light string through the external pin, The cxle86155 can meet the requirements of iec61000 class C Sub harmonic certification; cxle86155 has the function of line voltage compensation. When the mains power input increases, the IC automatically feeds back the current reduction to ensure the linear adjustment rate of 1% w / 10V; cxle86155 has the function of over temperature protection, which reduces the output current when the system temperature is too high to achieve the effect of low temperature. The over temperature protection point is wafer temperature 135 ℃, and the feedback to esop8 pin is 95 ℃. (the difference between cxle86155 and cxle86156 is that PWM dimming function foot is added) PWM dimming meets thd sub harmonic certification; four section led high-voltage linear drive IC, esop8 package; 90v-135v / 180v-260v working voltage range; 220V single maximum drive power of 12.5W; high power factor, no EMI problem; IC parallel connection, convenient for high-power industrial and mining lights, floodlights.

系统上电后,D1通过内部的高压JFET给芯片供电,当D1电压超过30V后芯片内部电压稳定,芯片开始工作。CXLE86155 根据整流波形的电压变化选择特定的恒流模块导通,从而改变接入的LED灯数:当输入电压较低时,有部分LED灯点亮;在输入电压较高时,大部分或全部LED灯都点亮。和单段高压线性恒流驱动的方案相比,CXLE86155 不需要填谷电容,具有高功率因数和低谐波失真,同时可以在整个交流周期内,增加LED灯的点亮时间,从而提高LED的利用率和总输出流明数。nFj嘉泰姆
