5v 3a Power Supply Circuit Diagram

To protect the circuit transformer rectifier capacitor filter an led indicator and the regulator ic.

5v 3a power supply circuit diagram.

This is a schematic of a simple dc 12v 3a power supply circuit using 2n3055 transistor. Voltage and frequency can depend on your country fuse. 5v 3a power supply circuit using lm350t how it works. The input voltage of 5v can be obtained from any usb port of laptop computer or a charger adapter.

According to the original principles choose capacitances 2 200 uf per 1a output current. Circuit diagram of 5v dc power supply below is the circuit diagram for the said project. The circuit schematic is given below. A lot of 6v supply diagrams.

12v to 4 5v 6v 9v converter. You get the main supply. This circuit can be very useful on the places where you want high current like 3a. The circuit is built by around icl7660 u1 along with two capacitors c1 and c2.

1 5v 3v adapter usb to 1 5v or 3v converter circuit small uninterruptible ups. Working on the unregulated power supply is similar to the circuit above. A 9v transformer steps down the main voltage 1a bridge rectifies it and capacitor c1 filters it and 7805 regulates it to produce a steady 5volt dc. But we added 3 filter capacitors in parallel resulting in combined capacitance is 6 600uf.

Output currents up to 1a can be drawn from the ic provided that there is a proper heat sink. Digital dc regulator if you are looking for 5v dc power supply for the digital. The complete 5v power supply circuit diagram using icl760 is shown below. Circuit diagram with parts list.

Many ideas of 12v and 5v dual power supply circuit diagram at 3a max. 5v power supplies digital power supplies.
