Just about everything I deal with is powered by 24 volts.

Something I hadn't found much information on is a good, industrial, 5 volt power supply that will allow 150-200 ma. or so to run a pic and a few components.

It would have an Automotive type 24 volt nominal input. For example, powered from a 24 volt power system on an industrial engine with a standard battery and alternator charging system.

Most of these range 18 to 30 vdc and are pretty noisy due to the alternator. I have seen numerous people stretch a 7805 out that far but I would be leary of the reliability.

There thousands of switchers out there, and some of them require more components than the main application circuit. The last couple I picked out, looked simple on paper, until I started pricing inductors and such, wow!

Not being real familiar with switchers I was wondering if anyone here had there favorite power supply they could recommend.
