I am not sure how to ask my question. There seems to be pages of account sign in info to ask a question?
I think your FemtoBuck LED Driver, COM-13716 is what I want. I have a Cree MX3AWT-A1-0000-000E50 surface mount LED. It has a forward voltage of 3.7 volts, and a forward current of 350 ma. It has a power rating of 2 watts. I believe your FemtoBuck LED Driver, COM-13716 is all I need to power it. I can supply 12 volts (for example), which is above the 7volts I think your product requires. So my question is: with a 12 volt supply feeding your Femtobuck, and my LED connected to the output of your FemtoBuck, is that all I need to power the LED?
