CXLE81113 CXLE81114模式的DC控制器驱动12个串并联配置每个串中有多个LED串联连接WM输入信号或直流输入信号实现PWM调光频率可由外部设置电容器编程

产品简介

CXLE81113/4

The CXLE81113 CXLE81114 is current mode DC/DC controller that drives up to 12 strings connected in parallel configuration with multiple LEDs in each string connected in series. External current sense resistor and slope compensation resistor make it flexible for various applications. PWM dimming is implemented with external PWM input signal or DC input signal. The dimming frequency can be programmed by an external setting capacitor. The CXLE81113/4 includes hiccup protection from short circuits, with automatic recovery after the fault condition is cleared. The CXLE81113/4 is available in a SOP-28, TSSOP-28 (FD) and TQFN5X5-28 package.
