LED驱动器/恒定电流源:

经济高效、值得信赖且简单易用

我们的线性恒流LED驱动器是一种简单强大的解决方案,可驱动高达250 mA的低功率和中功率LED,在不断增长的LED市场中用于绝大多数应用。符合AEC-Q101标准的NCR器件简单易用、安全可靠、经济高效且不影响EMC。它们减少了电路板空间和器件数量,可提供10-50 mA的稳定输出电流。LED驱动器/恒定电流源有五个封装选项:SOT23、SOT353、SOT457、SOT223和DFN2020D-6。

特性

  • 高电流精度
  • 能承受高功率(高达1250mW),提高稳健性
  • 电源电压高达75V
  • 并联驱动器可用于提升电流能力
  • 符合AEC-Q101标准
  • Tj = 150 ℃
  • 带可湿锡焊接侧焊盘的无引脚封装方案,便于进行自动光学检测(AOI)
  • 节省空间且面向未来
  • 易于实施
  • 多源支持

应用

  • 恒定电流源
  • 通用和工业照明
  • 消费类电子产品
  • 汽车内饰灯和外饰灯
    (门把手、仪表盘、牌照灯、指示灯、尾灯)
