Went with a KA3406 DC/DC converter pulled off an old motherboard, seems to
be working fine, had to play with the charge caps a bit to get what I wanted
but lost the heat for sure!

Thanks

Not sure why this one is elluding me, but , I have a graphics display with
an led backlight drawing about 450ma @ 5v. While a large 7805 is rated for
an amp it's getting pretty hot even with a nice sized heat sink.

Any thoughts on another way to drive this backlight? I was thinking of
running it at 12v (it's going in a radio) and a dropping resistor. What
say?
