Simple 12v power supply circuit diagram.

The final project i wanted to build was a wall adapter with a usb socket to charge my iphone. But first i wanted to start by creating a simple circuit that converts from the main power voltage 220v or 110v to 5v. This circuit can be very useful on the places where you want high current like 3a. Many ideas of 12v and 5v dual power supply circuit diagram at 3a max.

1n5402 3a diode c1. 5v power supplies digital power supplies. Each of the schematic is very simple to construct and will function without problems if you respect the maximum power supply ratings. A lot of 6v supply diagrams.

It is very difficult to find that type of regulated ics which deliver that high current so this circuit will work on the places where. 1 5v 3v adapter usb to 1 5v or 3v converter circuit small uninterruptible ups. Here are 4 simple 12v power supply circuits with output voltages around 12v. The output current of.
