Nice part, but I need isolation. And I don't need much regulation.

I need a simple half-bridge or full-bridge oscillator/driver chip. One
of the Ixys gate drivers might work.

I've x-rayed the commecial dc/dc converters and they are usually
hairball discrete transistor things. The Murata mouse-bite PCBs, with
the internal magnetics, are slick.
