LM25184: simulation

Nicola Mitrione
Prodigy 10 points
Part Number: LM25184
Other Parts Discussed in Thread: , PSPICE-FOR-TI

Tool/software:

Hello, 

I have tried to upload the library of LM25184 downloaded from TI but I saw is messing the file .libsig, I added to the library the files LM25184-Q1_TRANS.DSN,  LM25184-Q1_TRANS.lib,  LM25184-Q1_TRANS.opj,  LM25184-Q1_TRANS.olb. but still I'm not able to see yet that symbol into the library PSpice TI, how can simulate it into Spice?

I used the excel calculator but I would simulate with another tool ...

many thanks

Regards

Nicola

    Hi Nicola,

    Thank you for posting, and sorry for the delay.  I just downloaded the Pspice model at the following link: https://www.ti.com/lit/zip/snvmc00, and extracted the zip file, and I was able to open the model file, and run the simulation.  I am not sure why the libsig file is missing but it does not prevent you from run the simulation.

    By the way, I was using Pspice ver. 17.4 as suggested by the model file.

    Hope this helps.

    Regards,

    Hi Youhao, 

    thank you for your reply, I'm using PSpice for TI ver 23.1 and here looks like I'm not able to import that library, please do you have a link where I can download PSpice for TI the version 17.4 you tested?

    many thanks

    Regards

    Hi Nicola,

    I am using the full version 17.4, which has more capability than Pspice-for-TI.  However, the model should run with Pspice-for-TI.  I just do not have Pspice-for-TI installed on my computer, becasue the two installations may cause conflicts.

    Anyway, I asked our AE manager who has Pspice-fo-TI.  According to him, you will need to reduce the number of the signal probes so there are not more than 3.  Then, you should be able to run the simulation.    

    Regarding your above question on importing the library, sorry I am not sure I really understand it.  If you download the model package from TI.com, and save the file to a dedicated folder, then extract the zip file and let Windows to create all subfolders, you should be able to just open the OBJ file, and all model links should be automatically established.

    After opening the schematic, please do the following:

    1.  At "PSpice" tab, choose "Edit Simulation Profile"

    2. In the popped up window, click "Probe Window"

    3. Check "All Marker on open schematics". This will reset the signal probe settings that we used during the model development. 

    4. Click Apply and OK to close the setting window.

    5. Add up to three voltage or current markers to the schematic, then run the simulation.

    6. Move the markers to other circuit point if you want to monitor that signal. Remember: total three markers. 

    Hope this helps.
