Generate 22-30 volts from 12 Answered
I need to generate a voltage between 22 and 30 (for vfd tubes) from 12 volts (DC). It also has to have a minimum current output of 60mA (really 54, but I like to have some leeway). I really want to use something without an inductor (charge pump?) because I'm also driving nixies in the same area and I already have a lot going on. I would love to have something similar to the ICL7662 (essentially a voltage doubler, only uses a chip, 2 caps, and 2 diodes), but as far as I can tell it can't deliver enough power. I can't find any chip that's what I want... Help?
