TINA/Spice/TPS43061: Need unencrypted spice model.

Nikhil,

I'd prefer to use the spice program that I have because this TI chip is a part of a much larger project that has already been modeled. I'm currently using an Analog boost converter for this portion of the project but I wanted to see how this chip would perform in its place.

I received the spice model from the support staff but I had a question about a couple parameters in the model. Within that spice model there are several voltage dependent voltage sources that are modeled as follows:

E_U7 PWMOK 0 VALUE {LIMIT(V(N34828,N35569)*1E6,0,1)} _U7 N34828 N35569
+ 1G

I’m attempting to rewrite those circuit elements because my spice program is having difficulty interpreting it. It looks like it is a combination of a standard VDVS model and an arbitrary behavioral voltage source in the syntax of:

Exxx n+ n- value={<expression>} xxx nc+ nc- <gain>

But this is not a familiar syntax to me for PSpice or any other spice program. Can you elaborate on the intention of this line of code so I can possibly rework it into something my spice program can interpret?
