Auto-Standby circuit doesnt work as expected
Michaelaudio:
I found it out. It was the switching ic! (SN3257-Q1/TSSOP)
Does anyone know if a pin compatible switching ic exist?

I want it to work yes, I already changed connector nsfw on the pcb, spent hours of work just to get rid of some Problems (and 3 weeks to make schematic and layout) and now that everything works beside the stby circuit i want it to work no matter what, so yea I dont wanna redesign it or make it work another way than expected. I guess thats understandable.

mmmm.... no. If I discover my approach was wrong, I’d rather scrap it and start again with the right approach that will work well. Anything else is putting lipstick on a pig.

There's a rather more earthy phrase that comes to mind: 'gilding a turd'. Mind you, if you are willing to spend enough money that can literally be done. First freeze dry it, next resin impregnate it and fully cure, then plate it with electroless copper to build up a conductive layer, and follow on by electrolytic copper to the desired thickness. Finally send it out for the ENIG plating process we are all familiar with from PCB production. At the end of the day, however gilded, its still a turd, useless for anything except a scatological paperweight or a modern art exhibit.
