LM3481 glow discharge tube boost module, 3.2V-5V input

LM3481-based Glow Tube Boost Module - 1.0
 
Main Parameters
: Input: 3V - 5V;
Output: 150V - 170V, continuously adjustable
; Dimensions: 20mm × 20mm;
Version: 1.0
 
Introduction:
This module is used for power driving of glow tubes, converting low-voltage electricity into high-voltage electricity.
It has a simple structure, moderate size, and low manufacturing cost (under 20 RMB).
Its load-carrying capacity is decent. It can power 4 used QS27 tubes, and a brand new one should be able to power around 6.
(Load testing was not thorough; will be added later after testing.)

Future Plans
: 1. Move some components to the reverse side to further reduce size.
2. Try upgrading the circuit to improve conversion efficiency.
3. Optimize components to achieve cost reduction and efficiency improvement.
4. Try mass production and sales, controlling the price at 15-20 RMB, regardless of R&D costs, to drive down the price!
(It sounds crazy, but how will we know it won't work if we don't try? What if it succeeds!)
 
This
is currently only the first version, merely verifying the feasibility of the solution, so many aspects are still imperfect.
We will continue to improve it, reducing its size and increasing its efficiency! We also hope that you experts can offer valuable suggestions!
