The cxle86154 adopts the segmented linear constant current technology, which can set the driving current of the LED light string through the external pin, Built in high-voltage MOS full chip scheme and other optoelectronic integrated module production; LED light string adopts four segment structure, with high power factor and low harmonic distortion, and single LED light engine can adapt to the application requirements of 3-12w various LED photoelectric engines; cxle86154 has the function of line voltage compensation, when the municipal power input is increased, the IC internal automatic feedback current reduction, to ensure the linear adjustment rate of 1% w / 10V; cxle86154 has over temperature The function of protection is to reduce the output current when the system temperature is too high, so as to achieve the effect of temperature reduction. Set the over temperature point through the off chip resistance. When the control foot is suspended, the over temperature protection point is the wafer temperature of 135 ℃, and the feedback to esop8 pin is 95 ℃. After optimizing the internal circuit based on sds3538s, cxle86154 can perfectly adjust the light with AC120V thyristor of American Standard, and can realize high PF non stroboscopic application, which can ensure the stroboscopic depth is less than 30% in the range of 0-100%

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。CXLE86154 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,CXLE86154 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。
