5V 10A output switching power supply

The Schematic above shows a 10A power suplly 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.
