Now nobody flame me if this is a stupid idea, but it occured
to me that I could maks a simple switcher where I build up the
field in an inductor and then let it discharge into a string
of LEDs. Just an idea; I haven't worked out the details.

Like this?

That's exactly what I had in mind. No sense building one out
of seperate parts if an IC exists that does what I want. Thanks!
I especially like the "Internal 8.0 to 450V linear regulator"...

Also..Supertex has some other LED driving goodies too..
