5V DC / 10A Offline Switching Power Supply






Offline switching power supply which resulting 5VDC/10A output from 110/220V AC home power electric. See the parts list, there should be different MOSFET type for 110V anf 220V volatage input.

5V DC / 10A Offline Switching Power Supply circuit diagram


The schematic shows a 50-W power supply with a 5-V 10-A output. It is a flyback converter operating inside the continuous mode. The circuit has functionality of a main side and secondary side controller will full-protection from fault conditions such as overcurrent. When the fault condition has been removed, the power supply will go into the soft-start cycle just before recommencing normal operation.

About Power Supply
A power supply is a device that supplies electrical energy to one or more electric loads. The term of "power supply" is most commonly applied to devices that convert one form of electrical energy to another, though it may also refer to devices that convert another form of energy (e.g., mechanical, chemical, solar) to electrical energy.
A power supply may be implemented as a discrete, stand-alone device or as an integral device that is hardwired to its load. In the latter case, for example, low voltage DC power supplies are commonly integrated with their loads in devices such as computers and household electronics. More explanation about power supply can be found at wikipedia.org

This is the tutorial about "How to build an AC to DC power supply ". The video tutorial covers the basics of diodes, bridge rectifiers, and how to build simple unregulated AC to DC power supplies than can handle a few mA up to several Amps.
