using a $.37 MC34063ECN Switching Converters, Regulators & Controllers 3.0 to 40V DC-DC Cnv from mouser datasheet
The simplest way to reduce the voltage of a DC supply is to use a linear regulator (such as a 7805), but linear regulators waste energy as they operate by dissipating excess power as heat. Buck converters, on the other hand, can be remarkably efficient (95% or higher for integrated circuits), making them useful for tasks such as converting the main voltage in a computer (12 V in a desktop, 12-24 V in a laptop) down to the 0.8-1.8 volts needed by the processor. http://en.wikipedia.org/wiki/Buck_converter
