LCD Electroluminescent Backlight Driver Circuit

We show how to build a driver for a high-voltage electroluminescent backlight using an inductor, microcontroller, and a handful of other components.

I know from personal experience that high voltage circuits may cause permanent muscle and nerve damage.

i am hooking this clip and your site up to my community site when i get it up

Probably doesn't matter much, but all the datasheets I've seen say the drive frequency should be 400Hz...

wow thank you very very much.
