5V DC REGULATED PHONE CHARGER ELECTRONIC DIAGRAM
5V DC REGULATED PHONE CHARGER ELECTRONIC DIAGRAM Regulated phone charger which is used as an emergency charger for mobile phones with source from ordinary batteries, and works with 1.5V input DC voltage. At 5V, it can provide output to 70mA. If the current is drawn, the voltage will be drop. A006 microcontroller is used to create square wave which used to drive the Field Effect Transistor BBV93.
