Hello,
You all must think.. another topic about led drivers?.. Well, the problem is that I'm looking for a led driver that can operate from very low voltage. I want to run it on 2 (or even 1) NiMH cells, so lets say 1,8-3,2v.
The led I want to use is a Cree XM-L, (3A, ~3-4v=) but this is not definitive
I've already found the LTC3490 but this thing can only deliver up to 350mA. The sense resistor is internal, so an external fet is no option here.
Do you guys have an idea for a led driver? Ready made is also possible.
greets,
Stefan
