WEBENCH® Tools/WEBENCH-POWER-DESIGNER: Webench multiple outputs

Tool/software: WEBENCH® Design Tools

Hi,

I used Webench several times to design multiple output PSUs. Today I tried and the multiple outputs option is not available anymore?? :o

Is it somewhere else? How do I get to set Webench to generate all the reference designes for multiple outputs like it used to? Where I can then select one for the parametric table and the graph showing cost vs board space... etc?

Is there another link on the website?

Thank you

Steve,

We discontinued Flash tools on Jan 31, 2020 and discontinued the PMUs as part of that activity. There are some dual output devices that are still part of the HTML tool but you can design with those directly from the product folder panel only. For more details on the discontinuation of Flash tools, please check https://e2e.ti.com/support/tools/sim-hw-system-design/f/234/t/857843

Thank you Amod,

so how can I design multiple output PSUs "automatically" (using a tool like the old webench)? Can you please provide an explenation and link?

Thank you

Steve

I clicked on the Webench link in that page you sent but it does not work:

Hi Steve,

It is actually an e2e link for a post that gives details on discontinued products and also replacement tools, if any. Can you please try this link again: https://e2e.ti.com/support/tools/sim-hw-system-design/f/234/t/857843

The tool that used to allow multiple output design was WEBENCH Power Architect. Now, that is replaced by Power for Processors tool. Unfortunately, this portal is not a direct replacement for WEBENCH Power Architect. The portal page is located at: http://www.ti.com/design-resources/design-tools-simulation/processor-fpga-power/overview.html

WOOOW... Who made such a stupid (to keep it extremely polite!!) decision? It is like going back 200 years...

You can only choose between processors so if you want to create your own multi-output PSU you cannot by the look of things... Is that correct? :o

Steve,

I will relay your feedback to the team as it is going to be of great help in deciding the future developments of the tool.

You are correct that custom multiple output PSU designs cannot be created at the moment. The power for processors tool will help with processor and FPGA power supply designs only. One tedious way around would be to split input and output requirements and use the single output power designer tool to get recommendations on ICs and the corresponding design.

Thank you Amod,

yes please make it very clear to them because just between us and our sister company design more than 40 different PCBs every year mostly requiring multiple PSUs (often with sequencing too) then I assume there must be tens of thousands if not hundreds of thousands of engineers and companies who are in the same position.

Also... Even those that are used for the processors, often need additional customisation...

IF from your internal stat that tool was not used as much (not idea if that is the case!) it might be a case of just promoting it more. I also think that there are tens of thousands of new electronic engineers graduating every year and they would also find that extremely useful. Just promote it more...

Thank you again...!! :)
