Hello, it's my first post here, so I hope it's the right topic.
I want to build compact constant current laser/LED drivers for different diodes in 1.8-5A range. I managed to do it using linear regulators or operational amplifiers but both method was very inefficient and they didn't really fit in the laser/flashlight case, so now I want to build a driver using a step down buck regulator. I found this product:
https://images.bonanzastatic.com/afu/images/a3ee/bffa/bd89_7115368102/__57.jpg
It seems small and very easy to build, but I have no idea what regulator ic is used on this board because the labels are removed. So, my question is, does anybody know a constant current buck regulator ic which is easy to use and can be used for this purpose?
Thanks in advance!
