    Does anyone know a simple way to build a high efficiency 12v to 5v converter? I built a power supply using a radio shack voltage regulator but the heat was too much for my application. From my internet search it appears that what I need is a switch mode power supply but as a relative newbee I don't know how to build one. Does anybody have a simple schematic of one? Thanks!

    Why don't you tell us what your load current requirement is?

    Sorry, brand new to this site. Thought I posted in the right area. Guess not!

    Huh? What makes you think this isn't the right place for your question? Because you were asked to supply a basic specification, to define what you need? We can't read your mind.

    Usually, we need such parameters such as input voltage range, output voltage (range), and a range of load current. Without these parameters, we could spend some time coming up with a solution that would not be appropriate for you.

    The MC34063 is a pretty nifty IC, but it has a limited output current range.
