  • RE: LM3406HV-Q1: buck led driver for motorbike light

    Resolved
    Hello Antonio, The LM3406HV is a 1.5A rated part. It can be setup to run 200 mA, it's not shown there since this is a higher current part. There are other similar parts such as the LM3402HV meant for lower current. If you need the Q-grade part and 75V…

  • LM3406HV: 2 LM3406 in parallel

    Part Number: LM3406HV Other Parts Discussed in Thread: LM3406 , LM3409 We need to drive a serie of 16 LEDs with 3A and more or less 3.3V. Can I use 2 LM3406 in parallel?

  • LM3406HV efficiency

    Other Parts Discussed in Thread: LM3406 I am investigating the efficiency of the driver LM3406HV. I am working with a demo board ( http://www.ti.com/lit/ug/snva407b/snva407b.pdf ). I am feeding 4 red LED with 0.356 A DC and 25 V. Each LED exhibits 2V…

  • RE: LM3406HV OUTPUT MOSFET

    That should work fine. Just make sure the DIM pin is low while the LEDs are switched from one to the other.
