FemtoBuck Li-Po battery LED driving

Post by Systembolaget » Mon Dec 17, 2018 6:56 am


I want to drive 34V 90mA, 180mA and 360mA COB LEDs with a FemtoBuck and a Li-Po battery and saw that the FemtoBuck needs 6V input minimum - a single cell 3.7V Li-Po battery won't be enough, so I need a 2S version with 7.4V for the input to be boosted to 34V.

Will that work?

Also, how could I reduce the constant current from the default 330mA down to 90 and 180mA?

Many thanks in advance!
