Tool/software: TINA-TI or Spice Models

Hello,

My customer is trying to use the unencrypted spice model for the LM53625M and is seeing several errors like this:

Questionable use of curly braces in "b§e_u6_abm152 u6_n16776386 0 v={if(v(u6_n16734279)>0.5,v(iswh),0)} "

Error: undefined symbol in: "if([v](u6_n16734279)>0.5,v(iswh),0)"

Any ideas?

Thanks,

Hi Michael,

I don't see this kind of error in PSpice. Please find below the snapshot of PSpice model file.

Are you exporting PSpice model to some other tool?

Thanks,

Somen

Hi Somen,

Thanks for the response, we were able to resolve it.

One other thing is the model good for Bode plot sweeping? The result (output at the load) seems incorrect when a small AC signal was applied to feedback path. Please advise.

Thanks,

Hi Michael,

The model which is currently available on Web supports only transient simulation. You will need an average model to run AC simulation. If you want that to be developed please get in touch with your local FAE.

Thanks,
Somen
