My MacBook has somewhat recently suffered a chip burning and giving out a puff of magic smoke. I don’t know what this chip does or what it goes to, but I’m not sure I want to turn the computer back on after this happened. Can someone with better skills than me help me understand what this chip goes to and why it fried?

@jay5113yaj Okay so your board is a 820-2327. Your board has extensive water damage and you do want to clean it off properly. It has plenty of corrosion on it to shorten out more components. A toothbrush and some +90% isopropyl alcohol will work wonders unless you have access to an ultrasonic cleaner. Mark the component that went up in smoke somehow on your picture. Right now the part with the 330C on it is a 33UH inductor and is a CDPH4D19FHF-SM component. It is part of your 3.425V Hot supply.
Looks like you have had a couple more going up in smoke…..
