CXLE8104

CXLE8104是一种连续模式感应降压转换器。它可以驱动单个或多个串联LED。CXLE8104包括输出开关和高压侧输出电流感应电路,该电路使用外部电阻器设置平均输出电流。输出电流也可以通过向“ADJ”引脚施加外部信号来调整。ADJ引脚将接受直流电压或脉冲宽度调制波形。PWM滤波器组件包含在芯片中。在ADJ引脚上施加低于0.2V的电压将关闭输出。

一.产品概述O2a嘉泰姆


  The CXLE8104 is a continuous mode inductive step down converter. It can driving single or multiple series connected LEDs. The CXLE8104 includes the output switch and a high-side output current sensing circuit, which use an external resistor to set the average output current. Output current can also be adjusted by applying an external signal to the ‘ADJ’ pin. The ADJ pin will accept either a DC voltage or a PWM waveform. The PWM filter components are contained within the chip. Applying a voltage under 0.2V to the ADJ pin will turn off the output. O2a嘉泰姆
      The CXLE8104 is available in the SOT89-5L package and provides space-saving PCB for the application fields. O2a嘉泰姆
