Tool/software: WEBENCH® Design Tools
I reran the default design (Vin= 360 to 400 Vout =24V IOUT=10A temp=30) for the UCC256301 and this time it picked some Infineon FETs. I then changed only the outputs to VOUT=48 and IOUT= 5A. In the Webench design it hangs up with the progress scrollbar continuously going. I let it run for 2 hours with no results. Can you explain why this simple change would make webench hang up. When I make this change using the design spreadsheet for the UCC256301 the only thing that changes is the turns ratio of the transformer.
