I didn't mean that you shouldn't use a boost converter - back in the RS-232 days the Maxim max232 chip saved a tremendous number of parts (otherwise you needed a +/-12VDC power supply to drive the signal wires. The idea of the IC's Vcc following the coil's transient is a bit scary and I wouldn't design that into a system.
