If you see this happening with your control circuit then I’d recommend increasing your inductor value. I tried boosting a 3.3V->24V, but the 300uH inductor saturated and the output voltage was capped at 18V. You could easily adapt this to work for nixie tubes. I could increase this value to something meaningful, but I didn’t have a suitable resistor that wouldn’t burn up. 100V is possible as already shown, but the output current was only at 10mA. You can feel the heat radiating off the package. The 150 Ohm 5W resistor will get hot during testing.
