While thinking of a way to make a super-compact, 22.4V > 75kV @ 1.5kW power source I stumbled across this rather awesome full bridge IC from intersil.

I've ordered a few of them; will eventually let everyone know if they are any good. smile

How come you are over a million and a half miles farther from Sol than the rest of us?

Finally got this IC soldered into DIP form, hopefully I get around to playing with it.

The upper drives are not isolated and fixed at 50% duty cycle, likely they are designed for use with GDTs. All adjustments are done by varying the lower side duty cycle (something Steve did in his lighting gun...?).

Also has synchronous rectifier outputs.
