Hello there everyone,
I'm looking for a solution to build a DC/DC step up converter from 9V to 150V or 200V to drive a vaccum tube (12AX7-like), and Io = 200mA. I have already searched the internet but didn't find any similar design. I also tried the webench tool from TI/National.
I was wondering if I'll need to use a transformer to achieve higher voltages. If so, what are the specifications I need?; can I find a commercial component or do I need to buy a custom one?
Also, if possible, using PTH components.
Thanks in advance,
André.
