Cxle86109 is a high efficiency, step-down high brightness LED constant current driver chip. Built in power MOS tube, especially suitable for LED Driver with 12 ~ 60V wide input voltage range

Cxle86109 is a high efficiency, step-down high brightness LED constant current driver chip. Built in power MOS tube, especially suitable for LED Driver with 12 ~ 60V wide input voltage range.
Cxle86109 adopts the peak current control mode with fixed off time, and its working frequency can reach 1MHz at most, which can reduce the volume of external inductance and filter capacitance, improve efficiency and save PCB area. The working frequency can be adjusted by the external RC capacitor or according to the user's requirements. Add PWM signal at en end to adjust the brightness of LED lamp. Linear dimming can be set at FB end.
Cxle86109 sets the current flowing through the LED lamp by adjusting the resistance value of the external current detection resistor, so as to set the brightness of the LED lamp. The current flowing through the LED lamp can vary from tens of Ma to 4a. (large heat dissipation area)

一.产品概述nhH嘉泰姆


   CXLE86109是一款高效率,降压型高亮度LED灯恒流驱动芯片。内置功率MOS管,尤其适合12~60V宽输入电压范围的LED驱动。nhH嘉泰姆

   CXLE86109采用固定关断时间的峰值电流控制方式,其工作频率最高可达1MHz,可使外部电感和滤波电容体积减小,效率提高,节省PCB面积。可通过外部RC电容进行调节工作频率也可根据用户要求进行调节。在EN端加PWM信号,可调节LED灯的亮度。FB端可设定线性调光。nhH嘉泰姆

  CXLE86109通过调节外置电流检测电阻的阻值来设置流过LED灯的电流,从而设置LED灯的亮度,流过LED 灯的电流可从几十毫安到4A变化。(散热面积大);nhH嘉泰姆

 CXLE86109采用ESOP-14/PP封装。散热片内置接SW脚。  nhH嘉泰姆
