UCC28070: Pspice simulation file

Hi,

Sorry i miss that

However while trafering this pspice model to simetrix , i don't know how i will reconfigure the missing pins CDR,RDM an GND. The picture in Red color is the symbol iam getting thru the simertrx model conversion process

Jacob

Hi Jacob,

These models were created years back by our modeling group. The best explanations I can find regarding CDR, RDM, F_KHZ, IRIPA and IRIPB are from their E2E posts. Here are several below:

Thanks Ray, Let me review these attachements

Ray,

Myunderstading after reading the attached link is that , the model i tried to use is an average model and i canot used it in transient as a model for transient simulation. How ever in one of the link it says there is a published transient model available. Can you help me to get transient model for the above part

Jacob

Hi Jacob, I believe the average model of the part would also be used for transients simulation configuration.  I do find some other simulation files in our repository, including some load step and line step (transient sims) and they just use the average model.

So, to my knowledge, there is no difference in the controller model for the different sims.

Let me know if this make sense or if I may be missing what you're looking for.

Ray,

Will get back to on this

Jacob

Hi Jacob,

It's been three weeks since our last correspondence so I assume this has been resolved.  I will close out this thread but if you have further questions, please go ahead and submit a new E2E thread.

Regards,

Ray
