Had a 2019 MacBook Pro logic board give up the ghost last Tuesday
Customer brought it in, said it just died. No liquid damage, nothing obvious. I spent three hours checking voltages and found a short on a 1.8V rail. Replaced the specific power IC, part number CD3215B12. It powered on for ten minutes, then the same fault came back. I think Apple's design on these is just flawed. Anyone else run into this specific chip failing repeatedly?

Those chips are absolute garbage, always fail.

Honestly nancy475, I've had the total opposite luck. The ones in my old gaming rig ran for five years without a hiccup, and I'm still using a couple in a media server. Maybe you got a bad batch? I've seen more issues with the power supply cooking them than the chips just dying on their own.
