WEBENCH® Tools/LM25116: Part support, simulation did not run

bennie murah
Prodigy 10 points

Part Number: LM25116
Other Parts Discussed in Thread: TPS54340, , LM25145

Tool/software: WEBENCH® Design Tools

Is the LM25116 not recommended for new designs?  I tried to run a design in Webench and it would not simulate.  When I tried to modify the inductor value there was only one inductor to choose from.  It appears that the part is not being supported in Webench.  I wanted a higher voltage part that has a synchronous rectifier.  When I simulated with the TPS54340 the diode had the majority of the losses.

    Hello Bennie 

    I was able to create a design for LM25116  and WEBENCH provided multiple inductor options for me to change in the Customize Screen (Att for your reference)

    And I was able to run the simulations as well. I am not sure why you were not able to change the inductor and run the simulations. Can you please share the design using the share design feature?

    Hi Bennie,

    I do see LM25145 recommended for new designs when I land on the LM25116 product page so this is a good alternative if you are looking for sync rectification and high input voltage. Given that, LM25116 is still supported within WEBENCH. Can you please share your design inputs or even better if you can share your design public URL, then we can check what is going on.

    Regards,
