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:

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.
