USB cold-cathode UVC/neon driver - with schematic

Quite a smart little module. It's a surface mount cold cathode driver intended for use with UVC/ozone sterilisation tubes. But it will potentially drive other short neon tubes about 400mm/16" long.

The circuitry is very similar to the classic cold cathode drivers intended for providing illumination in PC cases and in some arcade games. But the use of SMD components makes it look quite neat.
It can theoretically drive two tubes if you add another capacitor to the output.

This matched set of tube and driver came from AliExpress:-

(Or try searching for item 1005004618501197 )
You can buy the bare tubes or the tube and driver together.
