This is a very cost effective switching regulator setup. It has been transcribed from [here](http://www.fiz-ix.com/2012/11/an-efficient-low-power-arduino-switching-voltage-regulator/)
The values have been changed from that original project to output 5v instead of 3.3
This has yet to be tested, but will be included in my next project
This should be capable of 1.5A output, but again, untested.
This board is a exact copy of the XL7015 buck converter.
XL7015 DC-DC step-down module is a high efficiency, high voltage buck DC-DC converter, and it can offer max 0.8A output current capacity, low ripple wave, excellent linearity adjustment rate and load adjustment rate. Its max input voltage can be up to 80V, far higher than 2596 module. The chip is built-in multiple protection...
This circuit uses the Buck/Boost Converter circuit for typically for use in a lab bench power supply. It features both adjustable voltage AND current using potentiometers.
Without a buck/boost converter,a computer power supply can only provide a 3.3V, 5V and 12 supply lines. With the buck/boost converter created with the aid of a 555 timer, adjustable voltage is allowed. A simple transistor is us...
