MT3608 booster in CC mode.

[Fabiosapplou]

Hi guys, I would like to know if any of you have any idea on how do I make a MT3608 in to a constant current mode, I’ve tried using a LM358 as differential amp on a 0.33R on the output feeding a 0.6v Vref on to the feedback pin of the MT3608 ic, but I don’t seem to be able to get it working. I have not seen anyone doing it but i think it should be possible though, probably my design it’s no good. Any help? Thank you.
