TPS2640: layout

?? ??

Part Number: TPS2640

Tool/software:

Hi,

I have questions about layout.

In the case of a 4-layer PCB, how should the inner layers be configured?

Should the areas where the TOP layer has the RTN pattern also have the RTN pattern on layers 2 and 3?

Also, how much area should be allocated for the RTN pattern?

Hello,

Yes, you can keep RTN in middle layer.

Not necessary to keep same RTN area in different layers

Thanks

Hi Amrit,

What is the minimum area in mm² that should be allocated for the RTN pattern?

Hello,

sorry for the delay.

There is no such minimum area. Please take reference from datasheet or EVM layout.
