The CXLE8120 regulator is fixed frequency PWM Boost (step-up) LED constant current driver, capable of driving Series 1W/3W/5W LED units with excellent line and load regulation

The CXLE8120 regulator is fixed frequency PWM Boost (step-up) LED constant current driver, capable of driving Series 1W/3W/5W LED units with excellent line and load regulation. The regulator is simple to use because it includes internal frequency compensation and a fixed-frequency oscillator so that it requires a minimum number of external components to work. The CXLE8120 could directly drive 16 Series 1W/3W LED units at VIN=24V . The PWM control circuit is able to adjust the duty ratio linearly from 0 to 90%. An enable function, an over current protection function is built inside. An internal compensation block is built in to minimize external component count.

   产品概述 返回TOP3Iu嘉泰姆

 CXLE8120 演示板用来演示升压高效率驱动 LED 全集成开关型变换器CXLE8120。

此设计是在直流输入电压为 5V-32V 时，最大输出电压可达 60V 的 LED 驱动；

最大开关电流 5A，系统转换效率最高可到 90%以上；CXLE8120 采用60V高压

制造工艺，内部集成高压功率 MOSFET 开关管，具有转换效率高，系统元件少，

可靠性高，安全性高等优点。

演示板可以演示CXLE8120 的若干特性，包括改变 RCS 阻值来实现对于系统

恒流控制，使用EN引脚进行系统的开关控制。
