Mini 5V Step-down board


I needed 5 volts for the micro-controller and display boards in the V2 charger from the 20V source that the charger boards themselves use. I decided to use an MC34063 I had lying around and designed this miniature board for it. Input cap, output cap, schottky, inductor and a current sense resistor. That's all there is to it. Works fine!
