interesting,  has potential to be used for DIY projects.
nothing like a DC to DC converter...

No mention of output ripple in the spec but I guess that is not too relevant for Nixie tubes.

I just noticed ha also modifies a commercial off line switcher to provide 180V at up to 230mA. Maybe he could do a version that does 250V at 160mA?

yes no mention of ripple.  but interesting none the less.  I had an idea for using Nixie tubes as part of a stepped volume control, each step as you increase in volume is another number in the nixie.

I've had a lot of success with Nixie PSU's, especially the SMPS designs.  Mostly because the ripple frequency is (typically) quite high:  in one design I adapted, the minimum ripple frequency has approximately 53kHz, and the maximum was near 250kHz.  This means RC and LC filtering is substantially more effective (like 70-80dB) as compared to filtering typical 100Hz/120Hz ripple.

Which designs did you try?

I have been meaning to try this one. The BOM cost is pretty high tho. https://desmith.net/NMdS/Electronics/NixiePSU.html



If noise and ripple is an issue, easy enough to follow it up with a linear regulator. :)

This one is a bit cheaper to build. I have a couple of pcbs left if somebody is interested.
