I've used the eDesignSuite to design a power supply using a VIPer38LE.  I'm verifying results and I'm having difficulty getting to the same primary inductance the design suite is.  Can someone get that info to me?  I am currently using the formulas in the Fairchild Application Note AN4137.

Thank You!

Tom
