Cxle8746 is a high voltage CFL control integrated circuit which uses half bridge structure to drive compact fluorescent lamp provides a simple and integrated lighting control scheme

The cxle8746 adopts RMS current control. The chip calculates the RMS current to change the frequency, so that the RMS current is constant, so as to ensure the constant lamp current and IC loss. The normal half bridge lamp current can be set by detecting the resistance RCS.

一.产品概述KkU嘉泰姆


    CXLE8746是一款高压CFL控制集成电路,采用半桥结构,用于驱动紧凑型荧光灯。CXLE8746提供了简单一体化的照明控制方案,适用于 220V工频电压输入和各种功率范围的灯管。 KkU嘉泰姆
   CXLE8746采用RMS电流控制,芯片内部通过计算RMS电流以改变频率,从而使得
RMS电流为恒值,这样就保证了恒定的灯电流和 IC 损耗,正常半桥灯管电流可通过检测电阻RCS来设定。 KkU嘉泰姆

   CXLE8746集成了多种保护功能:预热功能可调节的预热电流控制模式,调节预热时间和预热电流;电流饱和保护可在点火阶段提供专门饱和保护,这确保灯电感运行在饱和电流以下,且不超过半桥功率管的额定电流;在非标准条件下,过热保KkU嘉泰姆

护和电容模式保护会对电路进行检测,确保系统正常关闭和在灯管达到使用寿命时,处于安全状态。 KkU嘉泰姆
