You may want to consider other topologies, such as flyback. I spent a *LOT* of time debugging the DC-DC converter for my wristwatch project, with simulations and bench-testing. In the end, I got it working but my simulations were way-off because I did not have proper modeling of my

Hi Modern switchinh regulators don't 'just switch' they are more advanced, to determine a suitable inductor, you need to take a look at the datasheet of the IC. The converter from the link you showed, works perfectly, i rebuild that one a few times. If you have stability problems, you can

[neonixie-l] Boost converter inductor sizing question

2016-05-17 Thread ZY
Hello. I'm trying to build a boost converter for my project to boost 12V to 150-220V. I'm looking at various converter circuits online, like this one: http://desmith.net/NMdS/Electronics/NixiePSU.html, and they use inductors on the order of 100uH to 150uH, and use drivers that switch at

Hi all- Does anyone know which socket to use with DT-1704C tubes? It looks like a 9 pin mini but I was hoping to confirm. Thanks! -Dylan -- You received this message because you are subscribed to the Google Groups "neonixie-l" group. To unsubscribe from this group and stop receiving emails

I don't see a circuit in the link - it links on to a dead site. Can you post here? Some thoughts... Are you sure you are using IN-13 not IN-9 ? 13mA to fully light the tube is around what might be expected for a slightly cathode poisoned IN-9. It's easy to check even if the tube markings have

Yes, its only for testing if all digits work and look nice. With the rotary knob i can easy switch between the numbers. And i also have made it for when i take pictures of tubes, so i can place the tube in a fixed socket and switch between the digits remotely. -- You received this message
