I am trying to add this model of a tl431 to ltspice (http://www.audio-perfection.com/wp-content/uploads/TL431.zip) but I'm a little stuck. I looked in the help menu... but it didn't help much.
It works ok on my system.I am trying to add this model of a tl431 to ltspice (http://www.audio-perfection.com/wp-content/uploads/TL431.zip) but I'm a little stuck. I looked in the help menu... but it didn't help much.
HiTL431.asy is the symbol file which goes in the LTC\LTspiceIV\ lib\sym\references folder.
TL431ED.sub is the circuit model file which goes in the LTC\LTspiceIV\ lib\sub folder.
The others are various test and example files.
After placing these two files in the above referenced folders, restart LTspice. The TL431 should now show in the Component [References] parts list.
Unfortunately that symbol file does not include the reference to the model file so you have to reference it in a Spice Directive (press S) on the schematic as .lib Tl431ED.sub when you use the device in your schematic.
Alternately if you want to avoid that, use the Edit Attribute command of the T431.asy symbol file in LTspice and add:
TL431ED.sub for SpiceModel and
TL431ED for Value2.
