What would the Die Marking be for this part: EP5388QI What is this I marked in "red" by Xray? Please help me validate.

Datasheet shows top marking but not "Die" marking. Enclosed is "top" marking, Xray, and Die marking Does Intel know?

Hello Brandom,

In our Power regulators datasheet, Enpirion only shows the packaging top marking.

The package top marking that you attached is correct, and also the die ref number is correct but this is only for internal ref.

What you are marking in red squares is the internal inductor winding start and end points.

Regards,

Mostafa

    Mostafa,

    Ok, so is it normal for the "internal inductor winding start and end points" to be at different locations?

    I'm seeing this differ from part to part.

    The internal die marking "IC1012" can't be validated, correct?

    Let me know by day end today. I need to close out my case, thanks!!
