Hi Andy F,

thanks a lot for the files/link.

the only working device is tl494.

sg3524 .asc is missing,can not simulate without it.

Hi:

It works, I am using SG3525 model now. Edit sg3525.asy file with a text editor, check this line: SYMATTR SpiceModel ..\sym\Mylib\Mylib.lib, must be: SYMATTR SpiceModel Mylib.lib.
Put Mylib.lib inside lib folder of LTSpice. Restart the application.
You dont need asc. file only put the component inside your schematic. The .asy file edited line points to the sg3525 model inside the library.

Regards.

Thierry.
