Other Parts Discussed in Thread: LM3410

Which part would you recommend to use for the following:

Drive single LED string with 50-75mA of constant current.

Number of LEDs: 5 to 8 (1.4V per led)

Available Power Supply Voltages 12V (8min 14max) or 3.7V +/-5%.

Dimming is not required, just on or off.

Thanks.

Hello Lenny,

Perhaps somebody else will chime in here since most of what I work with is much higher power, but the one device I'm aware of that could do this in a simple fashion is the LM3410 if you use the 3.7V supply and configure it as a boost. I hope that helps.

Regards,

Clint

Thanks. I think the LM3410 will work. I got the eval board for it to try it out.
