Thank you for pointing that out. ? I made a mistake in the syntax when I typed it in the message. Yes there is only one pair of inductors in my circuit. Otherwise I would have used Kx (K1, K2,... Kn)

Hello all, I am in need of an LTSpice IC model of UC1834 (TI). Anyone who has ever come across one, kindly reply.

John Woodgate, I had a similar problem when using the ". inc". It was a month or two ago. I do not remember. I wanted to place the sample in the group, but gave LTspice is the same message as you. I

Hello, Running an dc/dc example named 3765.asc with slightly lowered feedback resistor (4.42 --> 4.2k) gives Vout appr. several times bigger than expected. Just the opposite what we should expect

John, It worked fine for me. There must be an issue with your PC. Rick

Hi John Woodgate. In my example, there is no need to use DOT commands ".inc" and ". Lib". LTspice allows it. Link to the library name within the symbol "Winding0.asy". Just run the simulation.

Hi Tony, I just need something for higher frequency, say 10MHz.

RL, I understand that, but there is no function of frequency shown at that link. If you don't think that is the case, double check it. Rick

Material permeability is directly related to inductance of the sample, if only the frequency changes in the test. RL

Falcon, You got lucky. Even though you were given the right syntax, you chose not to use it. The K statement should use the Kx syntax, where x is usually numeric, but must be unique. If there is only
