LM3414HV: LM3414 and LM3414HV Output Current Information

Part Number: LM3414HV
Other Parts Discussed in Thread: LM3414,


Since the procurement of LM3414MR is not good, we are considering using LM3414HVMRX as an alternative product.
When comparing the current values, it was confirmed that the LM3414HVMRX output was slightly lower. I couldn't judge from the datasheet, but is this result correct?
By the way, when I set the LED current output to 450mA, 300mA, and 100mA and compared the non-HV and HV products, the difference at 100mA was relatively large, which was greater than the ±3% accuracy described in the datasheet.
Also, is it possible to eliminate the difference between non-HV and HV products by changing the dimming control circuit, etc.?



  • hello Sir

    1. what is the current deviation between LM3414 and LM3414HV? does all LM3414HV show the same trend that is with smaller current output? As far as I know, the current rating of LM3414 and HV should be the same.

    2. has the operation under 100mA keeps in CCM mode?
