Voltage regulation circuit 12V to 5V in 5A range

Y...The selected TPS is difficult to handle by hand. Needs heatsinking on the PCB by special design. I do understand why you selected this one over the TPS565208, that is super easy to handle.

Amazing chips TI has...!

Definitely, that's why I did my best to mimic the "suggested" layout I posted above. I figure there's countless hours or even days put into that design.

I came up with this 4-layer PCB, top layer:




Both inner layers are identical:




And the bottom layer:




I did my best to use the same outlines, but I didn't have identical sized components, so I had to make due.
- Rpg goes to VCC on the datasheet drawing, but goes straight to 5Vout on the generated schematic.
- they have a single Cin cap, but mine is split into 2 using alternate parts.
- my inductor seems to be twice as large as theirs.

Also, the Webench schematic for 7-12Vin to 5A-5Vout didn't have these resistors:
- Rmode
- Renb
- Rent
So I don't have that trace from PGND going up to VIN.

The last thing I have to adjust is the copper layers; I remember reading something about needing 2 ounces top and bottom, and 1 ounce inners (or something like that - got reading to do).

Looks like this in 3D:
