I can't see any reason why this would ever be preferable to just using
the flat linear range (you certainly haven't articulated one, you're
just stating it). This seems like you are bodging around a limited
consumer driver, you should fix the consumer to cope with regulators
with lots of voltages - PWM regulators aren't the only ones with high
resolution steps.
