TINA/Spice/TPS54719: Availability of the TINA Model for simulation

Felix,

The PSpice models in the product folders for most power devices are encrypted and can only be used in PSpice version 15.7 or higher. I will ask to have the simulation export function from WEBENCH to be added to the TPS54719. Once available, you could export your WEBENCH design directly into TINA-TI.

Hi Britt,

Thanks for your quick reply.

I tried to convert the PSpice model to TINA based on the below steps that I read in another thread

"1.) Download the unencrypted PSpice model (transient for time based simulations, average for AC simulations)

2.) Use the New Macro Wizard to import the PSpice model into TINA-TI (Tools-->New Macro Wizard). Give the .TSM file a name, navigate to the .lib file where you have saved it on your computer and select the LM25116_TRANS model and use the Auto generate shape option.

3.) Save the .TSM file and insert it into your schematic

4.) Create your schematic based on the WEBENCH design."

It gave an error. Please refer the attached image.

Will it be possible to share the TINA model for this device so that I can construct the circuit and do the simulation?

Regards,

Felix.

Felix,

I understand your methodology. Unfortunately, per the previous message, the models are encrypted and cannot be used in TINA-TI. You would have to have the unencrypted PSpice model in order to follow that methodology.

We have added the device to the Simulation Export feature list in WEBENCH. I will update the post once the feature has been added to WEBENCH.

Hi Britt,

Thanks for the follow up.
Would it be possible for you to recommend to add another device of same family TPS54519 into the WEBENCH?
We are using this regulator also in our design.

Regards,
Felix.

Hi Felix,

We already have TINA-TI Transient model and multiple reference designs available for TPS54519 device. Please check in Tools and Software section of the part here.

We will update you on TPS54719 once the Sim Export feature is enabled on WEBENCH. 

Thanks!!

Best Regards,
