Unzip the file you provided into the subdirectory where you creating your LTSpice schematic. It contains two files.

Rename the one that ends in.lib to be Infineon.lib (to shorten its name). Xtreme rat. Delete the app note file (or not). To verify that LTSpice can find the lib file, do file/open/Infineon.lib. It should open in a text window inside LTSpice. Get the symbol file below NMOSsub.asy and save it in the subdirectory where you are creating your LTSpice schematic.

Create a schematic. When you get to where you want to insert one of the Infineon FETs, insert an instance of the NMOSsub.asy (not nmos). To do this, click on the little nand gate icon, and change the TOP DIRECTORY pull-down to point to your local subdirectory, and then select the NMOSsub.asy from the list of available symbols.

Remember to change it back if looking for a standard part. Now change the string subckt on the NMOS symbol to IPP65R190E6L3 (or any of the valid.subckt names in the lib file.) 6. Now add this directive to the schematic:.include. Infineon.lib 7.

You should have a simulatable circuit. I have included a small test file you can unzip into a clean subdirectory which you can look.

Click to expand.Hi MikeML I asked TI for an unencrypted model.

Their reply: 'only per our distributors' request and assessing their customers' projects'. Not very helpful as I need it fast. The irony is the transformer designed to work with this chip, the spice model is available in LTspice and the chip spice model only in Pspice. The reason I wanted to simulate is because my flyback SMPS prototype is not working because there's no voltage on the auxiliary to provide energy to the VDD to switch the IC on.

Any idea as to why this is? Thanks for your help.
