Other Parts Discussed in Thread: TPS54540, TPS54331

Tool/software: WEBENCH® Design Tools

Hello,

I cannot print schemati and BOM after chnaging inductor part. Detail is as follow

1. Enter the Webwnch from the TPS54540 pruct folder. (VIN 22.8 - 25.2V VOUT 5.0V IOUT 1.6A)

2. I can get PDF of schematic/BOM and Assembly documents by Print Report.

3. after simulation I can also get those files.

4. Then I change inductor part from default TDK to Bourns, I cannot print only schematic/BOM documant. I can print Assembly document.

I confirmd this issue not only with TPS54540 but also with TPS54331 on old and new version of Webench.

Hello Kiran,

Thank you very mych for your support.

I have one more question regarding difference between old and new version of Webench.

When I changed R, C, L values to meet customer requirment, simulation results were different between old and new version. I changed those parameters to same value. Only difference was that old version reported out of limit warning for L1 and Ccomp.

Could you explain me why this happen?

Best regards,

Hi Shibuya,

There seems to be difference in the steady state x-axis scale from flash to HTML and all other testbenches are matching well from flash to HTML.

We will work on the steady state simulation x-axis scale issue and let you know soon.

Thanks,

Hi Kumar,

Does it mean the classic version ( build in Flash) is correct?
Sorry for frequently asking, but I am not familier with software...
