The attached unencrypted model is not working. I have already seen that. Can you please check it.

It is not the exact unencrypted model of UCC28951. It is not having 24 pins. Can you please check and provide the correct model of UCC28951QPWRQ1.

Hello Shashank,

I'm sorry but that is the only model that I can find available for the UCC28951. The expert for this device is currently out of office.
I will refer this issue to him after he returns next week.

Regards,
Ulrich

Hello,

I have attached the unencrypted PSpice model for the UCC28950 and UCC28951 devices. I checked the model and it seems to be functioning correctly.

But this model is also not having all the 24 pins. THis model will work only for specific application. I want the full unencrypted 24 pin UCC28951 IC. Please provide if it is feasible.

Hello,

Sorry that I missed that the model does not have all 24 pins. This model however, is the only encrypted model that is available for this device.

There is an encrypted 24 pin model that has the full 24 pins that you can find at the following link. You can use this model with TI PSpice to simulate your design.
