Hello,
I did my due diligence of searching through 2 different manufacturers logo lists, searching all numbers, and reverse image searching both the logo and whole chip via google without success. Don't spend too much time on it, it's more of a hobby interest than something I desperately need to know. Based on the location of the 2 different chips, I'd guess that they are either buck convertors, or optocouplers, but the former is more likely.

Thanks!

 

Okay, I'm blind, it's a linear tech part. I still don't know what it is but that's a start.

 

Ah, found them!

The steps I took were to identify the manufacturer, then search for the manufacturers full expanded name plus all the numbers on the package plus the word "datasheet". I hope it helps someone.
