Hello. I'm working on a driver for my VFD filaments. Say I need a Vfilament
of 1.6V, and a current of 40mA, such as with a small VFD.
So far I have a square wave driver set up, basically for my two filament
pins I can alternate the two pins between 1.6 and 0 with some H bridge at
maybe 100KHz.
Since an extensive search of the web failed to turn up any actual
information about this display, I'll post my own findings here. The heater
voltage is 5V. Reasonable brightness requires an anode/grid voltage of
30-35V. Here's the pinout and footprint. Pins numbered from bottom left ACW
to top
