概述
  QX9920 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。
  QX9920采用固定off-time控制工作方式,其工作频率可高达2.5MHz,可使外部电感和滤波电容、体积减少,效率提高。
  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1.5安培变化。
       特性

 可编程LED驱动电流,编程范围为10mA到1.5 A
 高效率:90%
 输入电压范围:2.5V~400V
 工作频率可调:500KHz~2.5MHz
 驱动LED灯功能强:LED灯串可从1个到几百个LED高亮度灯
 亮度可PWM可调:通过EN端,调节LED灯亮度
       应用
  大功率LED照明设备
  LED灯杯
  LED筒灯
  LED手电筒
