Hello all,

I can't seem to find any data on both of these IC's.

They are part of the power rail in a Bluetooth speaker - I'm assuming they are buck converter IC's

The chip labelled " GV6XA" is 10 pin - this was shorted so has been removed and accidentally given to the gods of the floor. Luckily I took a picture before I removed it.

The chip labelled " XX7EA" is 16 pin - there doesn't appear to be a problem with this IC but its datasheet is just as hard to find, it would be nice to track it down.


Is anyone able to point me in the right direction on where I can look to find datasheets for these?

Any help / comments are hugely appreciated.

Thanks,
Carl

 

My guess is proprietary numbers as Google shows nothing. I suspect you have already tried that.

 

Yeah I've tried googling all sorts of things and descriptions... I've even browsed though all the buck converters on LCSC. It's definitely a tricky once. Fingers crossed someone with more experience than me can give me some more pointers on what to look for.

 

Custom chips are generally made by a semiconductor fab for a single customer. There is not likely to be any publicly available information or datasheet. The only possible source would be the manufacturer. So you might ask: "How do things get repaired"? The answer is they don't. Stuff just gets thrown away and replaced.

 

Oh I see. That's a real shame. Very handy to know though, thanks very much.
