该LM3414和LM3414HV是1A 60W *共阳极能够恒流降压LED驱动器。 他们是非常适合驱动3W单串HBLED高达96%的效率。 他们接受输入电压为4.5VDC至65VDC,并提供高达1A的LED平均精度为± 3%的电流。 集成低端N沟道功率MOSFET和电流感应元件实现,因为没有自举电容和外部电流传感电阻必须简单和低元件数​​电路。 外部小信号电阻到地提供了非常精细的LED电流调节,模拟调光以及热折返功能。

恒定开关频率操作简化了EMI。 无外部环路补偿网络是必要的。 专有的脉冲电平调制(PLM)控制在高转换效率和真正的平均LED电流调节方法的好处。 快速响应时间,实现优良的LED电流脉冲履行240赫兹256级调光分辨率为一般照明的要求。

该LM3414和LM3414HV可在ePSOP - 8和3mm x 3mm的LLP - 8封装。
