TPS54040: TPS54040DGQ: TOP MARKING

Hello,

I am not sure why the top mark would be different.

Where were these units bought? Did you purchase them on TI.com or from an authorized distributor....or somewhere else...?

Regards, 

Denislav

One of them has the logo of Texas. But the other has ‘TI’ ínstead of the logo. I am asking about the “TI” marking. 

Hello Maite, 

I see the markings in your image and again, I am not sure why one would be different. 

Can you confirm where those parts were purchased? 

Regards, 
Denislav

Hello Denislav,

They are from an authorised distributor but we are surprised about the one that has not the logo of Texas. We would like to know if there os a reason flor that. Thank u again

The parts I have seen on evaluation boards seem to have the logo. Can you share the complete shipping label?

It would look similar to this:

Thanks, 
Denislav

I don't have the shipping label because the reels have been assemblied.

Thanks,

Hello Maite,

In order to further investigate, we would need to get the lot information which could be on the label or the invoice of the material. If you don't have the label, please check your invoice from your authorized distributor. 

Regards, 

Denislav

Thank you. I will try to get it.

OK thank you Maite. We will wait for your response.
