Need help identifying specific PMIC.

[unimatrix93]

Dear Community,

I'm a repair technician and I trying to identify a damaged component made by STMicroelectronics.

Based on the surronding components and circuitry its a PMIC/DC-DC Coverter but I cannot find this specifc one.

As you can see, all the information is visible on the IC markings is XXC7-1. And it has a 7-pin configuration on a SOP8 package.

Can you please help me identify this component?

 

Thank you!

Welcome @unimatrix93, to the community!

If you look at the STMicroelectronics logo on our website, you won't notice any similarity, and it's also questionable whether the second letter is actually a T or rather a mirrored J. The logo looks like an Asian manufacturer to me.

Furthermore, the missing pin points to a driver device for high voltage in a flyback regulator, but our devices look completely different.

You abosuletely right. I mistaken the logo with ST. So it's more likely a Flyback IC instead of a basic DC-DC converter? 

 

Thank you very much!

It's just a guess that it's a flyback. In any case, I have not yet seen a device where a pin was missing due to the air and creepage distances required for high-voltage applications and it was not a switching regulator for mains voltage.

Maybe there's someone else who can recognise the logo. It looks familiar to me, but I can't remember who it was.

Good luck!
