I need the smallest smartphone charging Circuit that can be made, the input voltage would be from the wall socket (110-220 volt), and the output current would be of 1amp, 5 volt, 5W. Creative designs that come with smaller dimensions will be rewarded.
The circuit is a bridge rectifier.
Please write me, in case you can make some small dimensions. If so, write me the dimensions (all 3 dimensions), and how are you gonna make it ( important components,etc,etc) . Safety and availability of the material is so important for me as well.
Small dimensions are important are gonna be rewarded.
