That doesn't sound right - If you post your stack I'm sure one of us with more LTspice experience may be able to help. The LTspice Yahoo! group is also an excellent resource for advice - the LTspice developers hang out there and that's where the real knowledge is. Nick On Friday, 11 August

I am using an LM3478 library and a Wurth flex transformer library. I suspect that is where the time is going. I have zipped up the .asc file and the aformentioned libraries (though the Wurth ones were pulled out of the LTSpice library folder, so they are in the wrong place!). Hmm, I guess I

HI - You LM3478 symbol pinout was wrong - you've got pins 5 - 8 flipped... Its a slow deck for sure - I'll have a play with in in the next couple of days. Also attached slightly reformatted schematic to compensate for change in the ASY file. Annoying that the PSPICE model from TI has a

I tried running this version, but the simulation window doesn't open and I can't place probes on the circuit. I looked in the .asc file and fixed up the path to the wurth model, but it made no difference. I have no idea how to get that window back. Also, the values of caps that were uF became
