I am trying to simulate circuit from link: Nixie power supply, but I have come into some problems. I downloaded MC34063 from this forum and example in package is working perfectly. Below is my circuit in LTspice. But for my circuit there is no oscillation on swe output so Q1 and M1 is constantly in one state. As output voltage I got 3.6 V.
Here is digital version of my schematic file: circuit + mc34063 model
What am I missing? Not working is caused by wrong components, different from schematic? I don't get something about LTspice?
I am new to electronic and just pick this as exercise.
