Looking for a PSpice model

[ElectricWraith]

For an LM2907 FVC. I'm using MultiSim, and so far I've had no luck in finding a model to simulate a circuit I need to build around this chip. I can use OrCad as well if need be, but so far no luck with a model in that program either.
I think that the problem in finding it has something to do with the proprietary charge-pump method used, but I'm still hoping to find a model.

Anybody?

Hmm...

I did the model for you, you will find it here:
http://www.geocities.com/russlk/lm2907.jpg
http://www.geocities.com/russlk/LM2907.txt
The .jpg file is the schematic, the .txt file is the SPICE listing of the complete circuit to make it run, you can pick the subcircuit out of that. I have run it in ISPICE and Switcher CADIII.

It may be necessary to copy and paste the URL, geocities does not allow links.

I found an error in the SPICE listing, the file has been corrected - I hope!

I made a Switcher CAD symbol for the LM2907, you will find it at www.geocities.com/russlk/lm2907.bin
Well, the link does not work, send me a private message if you want a copy.
I had to change the file extension from .asy to .bin in order to upload it, you will have to change it back to .asy to use it.

Does any one have a valid LM2907 spice file, the geociyies link doesn't work
Thanks
