Other Parts Discussed in Thread: LM3410

Need a LED Driver (Boost: Vin-2.7-4.2V) that can push 8 LEDs ( in serial connection),

each LED have Vf (Voltage forward) = 3V max and If ( Current forward) =200mA.

It mean that for all LED (8 LEDs) the driver should be have 24V and 200mA.

Hello Eli,

The only one I am aware of that could do this is the LM3410.

It is look very OK but output voltage is very close to 24V.
The Absolute Maximum Ratings is 26.5V and the output voltage is 24V they are very close each to other.
If you will find Absolute Maximum Ratings 29V or 30V or over it will be great.

I found LM3410. Is it recommended for this design?

Hello Eli,

Yes, that is the only device I am aware of that fits the specs you need. If the LEDs are 3V max it should be ok.
