WEBENCH® Tools/LM2678: layout issue

Kenneth Tait

Part Number: LM2678

Tool/software: WEBENCH® Design Tools

Did webbench on LM2678 5V out at 4A 8-18V vin.

BOM looks ok, but layout is not correct. Pinout of part doesnot match the data sheet. CB should return to pin 6, looks like a trace to pin 3 instead. So what's wrong here?
