Maxim chip sounds nice, but the need for an inductor, diade, etc. can
be a pain in the butt, and it raises the required board space and
cost. 

Power Trends has a 3-pin switcher regulator with everything in one
package. Part replaceable for a linear heater, err, voltage regulator.
Efficiency is about 87%. Price is high though: $15 in qty 50
or more. Runs cool and solid. 

Is there any other part that is close to or equivalent to the Power
Trends part that is cheaper?
