Hello technical support,

Pls kindly help to check the die marking picture of LM2675MX-5.0/NOPB.

As show in below,one has a logo of national semiconductor and the other one dosen't have.

Could you please help confirm what caused this difference？

Looking forward to your reply.Thanks！

Hello

The difference you see on the die is due to different manufacturing sites.

We have two sites that manufacture this device and they use different die graffiti.

Hello

Thank you very much for your confirmation.

In addition,I want to confirm whether TI have issued an official PCN to explain this situation?

Thanks

Hello

There would be no PCN since nothing has changed.

The material is produced from two different manufacturing sites.

Thanks
