    Hi all, i came across this board while searching for a spice file of the popular SMPS PWM controller,
    http://electro4um.com/about692-asc.html
    However, copying and pasting that code and generating a part symbol for it in Orcad Pspice has generated a few errors, i assume its because i dont know what i'm doing when it comes to SPICE syntax. Anyone have this part or even a similar PWM controller spice model i can use to just close the loop on my simulation. Thanks.

    The warnings and errors seem to be regarding XTOF1 and XTOF2?

    Well, wasnt able to come up with the SPICE text file, but found this model for ltspice, can't use with Pspice, but i'll give ltspice a try.


    Code ( (Unknown Language)):

    My first advice was to try to find a model from TI, because they usually provide PSpice models when they do provide em. I couldn't find one for the 3842, however. I'm pretty sure they have one, because AEI makes all their models and made one for IsSpice.

    Sorry we couldn't be more help!

    Its okay...they wanted $300 for the model, along with others, they wouldnt jsut sell it individually. :eek:
    I'll stick to messing around with ltspice and that model.

    Yeah, I got the same story when I was trying to find a UC3808 model for IsSpice. Bummer.
