Dual channel, current limited driver
Good day to everyone, I am interested in purchasing a dual channel current limited 17 or 20 mm driver to drive one red LED and one infrared LED. I would also need a 20 mm dual pad PCB to mount the LEDs. But first things first, a driver and firmware are my first step. I look forward to all and any suggestions, ideas, replies. Thank you and everyone have a great day. Tom

Tterev3 had some for sale at some point I believe, not anymore, you can still try to contact him for more info as he has made a lot of multi channel drivers.

I’m working on a buck-boost based one but the ICs I ordered changed to backordered once I placed my order Facepalm

These chip shortages are even affecting us Sad I was going to order some charging ICs for a diy 10180 charger I’m making but then someone cleared out all 250+ from digikey and the thousands from mouser.

I noticed the SC70 versions of op-amp OPA333 was running out so I stocked up. Glad I did, there where all gone a day later on Mouser and new stock is not expected until mid November.
