About MPM3683-7 footprint

Integrated Inductor Power Modules

Hi, I would like to confirm some details regarding the footprint of the MPM3683-7.

In the datasheet, there is an indication of a “keep-out area”, but the drawing available on your website does not show this indication.
Which one should we follow?

[Additional information]
The datasheet instructs us to connect the SW pins (pins 14, 15, 16, 19, 20, and 28) to large copper planes in order to improve thermal performance.
However, if the keep-out area is applied, this connection would be restricted.

Also, although it is a different model number, we found that a similar product, MPM3683-10, does not specify such a keep-out area, and in the recommended PCB layout in its datasheet, these pins are connected with wide copper traces.

Could you please clarify which information is correct?

Hi Masahiro,

I’ll have an MPS FAE reach out to you over email to answer your questions. Please reach out again if you have not received this communication in a few days.

Best,

Tyler
