LTSpice installing encrypted third party MOSFET models.

[Lightium]

I asked littlefuse.com for the spice model of a particular MOSFET. I was given a similar model and told that the model I was looking for wasn't ready. I don't know how to use these. Can someone help or point me in the right direction?

I just copied all the files to the cmp directory and made a schematic, but I still can't get it to function correctly. Please help.

Usually, the .OLB is for Orcad.

The .lib might be used as its generally a pspice ascii file.
If you post them, I can check it.

Thank you. I have to add it as a zip cause ETO won't take the individual files.

Thank you.

Nevermind.

Use the attached file.

I've added spice code at the top of the file that correctly re-maps the .subckt pins so you can use the native LTspice NMOS symbol.

Be aware:
1. Change the LTspice symbol "Prefix" attribute to "X" (w/o quotes)
2. Change the LTspice symbol "Value" attribute to "IXFN520N07" (w/o quotes)
3. Add this (directive) statement to the schematic:

.inc ixfn520n075t2_LTspice.txt

So LTpice can find and read the file.

Sweet, now I have a new device to work with. Here's something I just through together.
Thanks again.
