SwitcherCAD III by Linear Technologoies does not currently have a
transformer in its components menu.
Does anybody know if I can find a switching power supply type transformer
that I can import into SwithcerCAD?
Thanks -Ira
Look in Help/FAQs/Transformer Model.
Here is a starter. You need to insert the appropriate values according to
your particular transformer...
