LM25116: No convergence in Pspice for TI

Hello Andres

Would you please send me the simulation files ?
- Eric Lee

Eric can you show me how to upload the file? Because I clicked on Insert -> Image/video/file and it is not working. Also I dragged the file and dropped it and nothing happended

Pspice_TI.zip

Ok I figured out that only accepts .zip files and not .7z

Here is the file

Hello Andres

DC-DC CONVERTER 80W.DSN file is corrupted. Can you send me again only the '.DSN' file ?

- Eric Lee

LM25116_30W.zip

I sent you again the file because I changed the name of the schematic and it seems an error when you do that. The new zip is a copy of the schematic with the same simulation.

Hello Andres 

Thanks for sharing the file. 

-Eric Lee

Hello Andres

I think you sent a wrong file. I still see the error. 

- Eric Lee

Sorry, can you try again? I tested this one several times and it opened without a problem

Test_LM25116_30W.zip

I don't get why is corrupted. I'm creating a new project everytime and just copy the schematic. I did what you told me and still it doesn't convergence the simulation. I create again the schematic without copy the design (I don't know if the other circuit had an system error and by copying it I was bringing the error as well)

also this is the image of my circuit 

Parameters are

Vin 24VDC

Vo 5.1V

Iout 6A

Fsw 330

ILripple 30%

Hello Andres 

Would you please let me know which PSPICE you are using and what's the version ?

- Eric Lee 

I'm using the last version of PSPICE for TI 2022. I downloaded last week.

Hello Andres 

I will give you an update later. I can install PSPICE for TI 2022 next week.

-Eric Lee

ok thanks for the help!

Hi Andres

You don't need to reply this post until I get the result next week.
