Cxle86104 is a high efficiency, step-down high brightness LED constant current driver chip. Three functions are integrated inside: full light, half light and explosion flash

Cxle86104 is a high efficiency, step-down high brightness LED constant current driver chip. Three functions are integrated inside: full light, half light and explosion flash. The mode switching among the three functions can be realized through the on-off of the power switch. No additional MCU or other control IC is required.
The cxle86104 adopts the peak current control mode with fixed off time, and its working frequency can reach up to 1MHz, which can reduce the volume of external inductance and filter capacitance, improve efficiency and save PCB area. The minimum turn off time is 620ns, which can be adjusted by the external RC capacitor, and the working frequency can also be adjusted according to the user's requirements

一.产品概述5K5嘉泰姆


   CXLE86104是一款高效率,降压型高亮度 LED 灯恒流驱动芯片。内部集成了三功能:全亮、半亮、爆闪。通过电源开关的通断即可实现三功能之间的模式切换。无需外加 MCU 或其他控制 IC。5K5嘉泰姆

   CXLE86104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。关断时间最小为620ns,并可通过外部RC电容进行调节,工作频率也可根据用户要求进行调节。5K5嘉泰姆

   CXLE86104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4.5安培变化。5K5嘉泰姆

   CXLE86104采用SOT23-6封装。 5K5嘉泰姆
