Scott Schenkel

Part Number: PMP8877

I was not able to locate any information indicating the layer stackup developed for this reference design. Would it be possible to access this information?

I wanted to follow up and see if there has been any progress here. Thank you.

Hello Scott & John,

just checked it, it's a 12-layers PCB;
that's needed to provide the windings for the planar transformer solution.
Could provide a PDF prt of the PCB if that helps...

Best regards, Bernd

Thank you for getting back to me. Specifically, I was curious what dielectric thickness and copper weights were used. I have not designed any a integrated xfmr before and suspected the layer spacing may be important. Also, I was curious what copper weight was needed to handle the current in the power path.

Thank you,

Scott

Hello Scott,

unfortunately the responsible designer left TI some time ago.
I'm not able to figure out anything regarding the PCB itself.

Sorry for this & best regards, Bernd
