Product Details
 概述

      QX5305 是一款高效率，稳定可靠的高亮度LED灯驱动控制IC，内置高精度比较器，off-time控制电路，恒流驱动控制电路等，特别适合大功率，多个高亮度LED灯串恒流驱动。
  QX5305采用固定off-time控制工作方式，其工作频率高达2MHz，可使外部电感和滤波电容、体积减少，效率提高。off-time最小时间，可通过外部电阻和电感进行设置，工作频率根据用户要求而改变。在EN端加PWM信号，可调节LED灯的亮度。
  通过调节外置的电阻，能控制高亮度LED灯的驱动电流，使LED灯亮度达到预期恒定亮度，流过高亮度LED灯的电流可从几毫安到2安培变化。
       特性
        可编程驱动电流
        高效率：最高达95%
        宽输入电压范围：2V~400V
        高工作频率：2 MHz
        驱动LED灯功能强：LED灯串可从1个到几十个LED高亮度灯
        亮度可调：通过EN端PWM，调节LED灯亮度
        LED灯电流5MA-2A
       应用范围
   干电池供电LED灯串
   LED灯杯
   RGB大显屏高亮度LED灯
   平板显示器LED背光灯
   恒流充电器控制
   通用恒流源
