Anybody know of a good way to switch pull -15V to ground using 3.3V and as little components as possible? In other words: I need a negative switch controlled with a positive voltage. That way I can control the LM5067 from a microprocessor.

How about a pnp transistor and resistor(s). 3.3V input goes thru resistor and emitter, base at ground, and collector to negative rail referenced input. Negative rail input may need a pulldown.
