Hi all,
I'm experimenting with a custom LED driver and am looking for at most 2A output to a single XP class emitter from a single 18650 (or similar) cell.
Normally I'd just design a board using 7135 chips however space is a little limited so I'm considering using a single voltage regulator hooked up to act as a constant current regulator. I want to control it via PWM. Can anyone with some better electronics chops than I recommend a suitable regulator to use?
I have an instructables link somewhere that tells me how to set up such a circuit but beats me if I can find it now that I want it Lol.
Anyway, any advice would be awesome.
Thanks,
- Matt
Edit: my title mentions buck drivers. That's a typo but I can't edit the title from my phone. Cheers.
