I was wondering if it would be possible to use a TPS54286 from TI to power either an Arduino micro or mini using an input, into the TPS54286 obviously, of 24v.
If I understood the datasheet correctly it creates a PWM signal , thus powering an Arduino using PWM???
Other thoughts on how to incorperate these Arduino boards into a 24v environment are also very much apriciated.

It shoudn't be so hard when you realizes what a carplug to usb converter costs nowadays. The truck versions convert 24v to 5v as well.....

Building your own switching regulator is difficult, you needs to choose the inductor very carefully and layout is critical. It's easier to use a ready-made DC-DC converter. There are lots to choose from, including cheap ones on ebay such as http://www.ebay.com/itm/LM2596-DC-DC-3-2-40V-to-1-5-35V-Step-Down-Adjustable-Converter-Power-Module-/300739026797?pt=LH_DefaultDomain_0&hash=item4605715f6d and more expensive ones from the major component distributors.
