USB Charger V2 using OnSemi lm2576 switching regulator. It will provide 5v 3amp output for charging I devices. There are resistor dividers for making the correct voltages on the d+ and d- . This layout is untested, but the schematic is fully tested and works well. There is one error on this board, it with the coil, it is layer out for an axial coil not the radial rl2444 that is on the silk. See v1 if you want to use the rl2444. I will update the description here with the correct coil when I get a chance. The correct coil should be coilcraft PCH-45X-683.
