ADuM3190 files missing from library (on Mac)

Thread Summary

The user encountered issues with the ADuM3190 and ADuM4190 LTSpice models being missing and a pin count mismatch error. The solution involved adding a spice directive to the schematic to include the ADuM3190B.sub model and correcting the path issues for MacOS, which resolved the simulation errors. The user successfully modeled the ADuM3190 in a flyback SSR configuration supporting a Pout range from 2x1W to 120W total.

Hello, 

couple if items

1. The ADuM3190 and 4190 are missing from LTSPICE. Not sure how ADI decides that certain models are to be omitted ..? 

2. so I used the ADuM3190 model as posted by ADI in the forum. 

Inserted the the model into Sub and lib folders (on mac) as i do w all others

It appears there is a miss match on pin count of the ADuM3190. It flags an error at start up.

Btw the ASY file name and the sub file name are different (ADuM3190B)

Perhaps I am doing something wrong. Please advise.

  • Since my ADuM3195 design is working well I decided to reduce BOM cost using the ADuM3190/4190 version. Please advise on the above questions thank you

  • Hi  

    Thank you for your inquiry. We are aware that the LTSpice model for the ADuM3190 is currently missing. Our team is actively working on restoring it. We apologize for the inconvenience.

    What kind of error are you experiencing at startup?

    One possible error you may have is "(3): This sub-circuit name is not defined."

     

    You can fix this error by adding the following spice directive to your schematic:

    .include ADuM3190B.sub

    To add a spice directive to your schematic, click on the ".t" icon on the toolbar and paste the above spice directive

     

    Let me know if you are able to run the simulation.

    Regards,
    Alessandro

  • Ciao  Alessandro 

    Thank you for the response. I do all my major development on two MAC OS machines M1 M2 etc.. I have PCs but only for running the PICO oscilloscopes PSPICE and few other apps. I prefer the LTSPICE mac os version much better...

    ad 1> OK is there a timeframe for including the ADuM3190 back into distribution? I am trying to replace the more expensive 3195/4195 w the 3190 (Also holds half the Vref than ADuM3195 and matches the latest Gen flyback controllers from ADI.

    ad 2> The issue is path i believe. LTSPICE for MacOS doesnot resolve the spice path properly. if the path contains a space. Which is the case w .../applications support/... for example. the .include statement throws an error. 

    I have the same thing with a series of MOSFETs from IFX. If i want this to work I have to essentially use a local file. by having to eliminate the path and placing the model in the directory. which causes files to be all ove rthe place and out of synch etc. 

    LMK if this will be fixed..? 

    Thank you 

    Kind Regards 

  • Ciao Alessandro, Mi scusi for all the messages... I wanted to make sure I am not wasting your time - you trying to trace something already solved.

    OK I rebuilt the symbol, fixed the path, and corrected all the internal model references etc.  Model now works fine. see attached .asc. (if you want to run it you would have to load a stray ADuM3190 model into the local path)

    It appears the ADuM3190 works fine in this configuration supporting a Pout range from  2x1W to 60W Pout total 120W. Have to model the loop gain, RHZP etc. in MATlab but this all looks good. thank you for your help. grazie mille

  • Hi Thomas,

    No issue at all, I'm glad you solved this issue and thanks for letting me know!

    Best regards,
