Hello TI Engineers,
I would like your assistance in reviewing a 4 Layer PCB Layout of a 5V Regulator Design for the TPS54202 Buck IC. Below is a screen shot of the Schematic and Layout; One version of the layout only shows the top (red) and bottom layer (blue) the other shows the two inner layers which are Ground Planes. The design was made with web bench design. The Layout was a combination of the layout generated by the web bench and the layout suggestion on the datasheet. Where I used the space between the input capacitor to route the SW Pin to the Inductor but I did not need to via down to the bottom layer to do the routing. The output capacitors are also connected to the ground plane where the ground pin of the IC is also connected to.
