5V 10A current output switching power supply

The circuit diagram shows a 10A current output power supply with a 5V output and with power 50W. It is a flyback converter operating in the continuous mode. The circuit features a primary side and secondary side controller with full protection from fault conditions such as overcurrent. After the fault condition has been removed the power supply will enter the soft start cycle before recomming normal operation. See other circuit adjustable power supply
