Other Parts Discussed in Thread: UCC28056, UCC28056EVM-296
Hi,
Do you have a gerber file for UCC28056 EVM-296, I want to understand how the layout was done. You can send it privately to my email.
Kind regards,
Bright

Hi,
Also, I would like to understand the dots on the schematic attached. Does it mean that they are connected together directly? or something else?
Kind regards,
Bright
Hello Bright,
I can attach the Gerber files here: UCC28056EVM-296_Gerbers.zip
At TI, they are viewable with Camtastic CAD software.
You can also view the bottom side of the board by clicking on the image in the UCC28056EVM-296 product folder: https://www.ti.com/tool/UCC28056EVM-296 . This board is a 2-layer board, but the layout is intended to serve as a model for a 1-layer board. Obviously, this EVM is not designed for maximum power density, rather it is spaced out for ease of probing, simple cooling, and evaluation of performance.
This image can show most of the interconnection intent, although the details around the controller IC are a bit obscure.
The dots in the schematic indicate direct connections. The lines approaching the dots are angled because 4-way connections are not allowed by TI drawing standards, only 3-way connections are allowed. The angles allow the components to be aligned vertically for cleaner viewing and understanding of the networks.

Hi Ulrich,
Thank you for the reply.
Are the jumpers for example, J5, J4 used because it is a single sided board layout? and not for any EMI reasons or loop inductance ?
Kind regards,
Bright
Hi Bright,
Yes, the jumpers are simply for implementing a 1-layer layout. No EMI or inductance, or any other reasons.
Regards,
Ulrich
