制造</span>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，</span>
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。</span>
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.pQz嘉泰姆
