WEBENCH® Tools/TPS54340: Layout for 6 layer PCB board

Pranav Dosajh

Part Number: TPS54340

Tool/software: WEBENCH® Design Tools

I have designed a 6 layer PCB board having configuration TOP--GROUND---SIGNAL----SIGNAL----POWER--BOTTOM is there any reference design for multi-layer PCB. or any document regarding connecting high voltage buck converters within multi-layer boards.

The low voltage buck converters work efficiently but I end up having grounding problems when converting high voltage to low voltage buck converters within the board.

Hi:

our EVM is 4 layer PCB ,https://www.ti.com/lit/ug/slvu794a/slvu794a.pdf

for PCB board, normally we will suggest follow EVM component placement . Placing the component at top and using Ground to isolated the noise from top.

below is some training video for DCDC layout, it introduce the ground placing , maybe will help you.

Thanks
