MP9428a datasheet or pinout?

[manu]

Hi,

I have a Sony bluetoth speaker srs-xb20 with a charging issue.
I suspect the Monolitic Power System chip MP9428a but I cannot find a datasheet nor a pinout.
The only source is their online dc/dc tool, so if you know this chip, I would be glad to have more infos.

Thanks!

Hi!
Try this picture from the attachment.
I know, it's not the same ic but try to identify the circuit and maybe this ic is the same pinout as yours.

Just give a try.

Let as know if this is or not good.

My best regards.
