A very simple 5 volt switching power supply electronic circuit project can be designed using FAN302HL highly integrated PWM controller integrated circuit, that provides several features to enhance the performance of general flyback converters.
The constant-current control, of the FAN302HL proprietary topology enables simplified circuit designs without secondary feedback circuitry for battery charger applications.
This 5 volt switching power supply electronic circuit project accepts a wide range input voltage from 90 to 265 VAC and will provide a 5 volt regulated output at a maximum output current of 1.2 ampere .
A proprietary Burst-Mode function with low operation current minimizes standby power consumption.

The FAN302HL controller also provides several like protections : VDD Over-Voltage Protection (Auto-Restart) ,VS Over-Voltage Protection (Latch Mode) , Fixed Over-Temperature Protection .
The most difficult part that is require in this project is the transformer.
W1 is four winds; for each wind of turns, refer to table bellow. Add one insulating tape between the first and second layers.
W2 is wound two layers and uses triple-insulated wire: end of positive fly line is 3.5cm, layer end of negative fly line is 2.5cm.
W3 is spares winding in one layer.
W4 is wound in the core of the outermost layer and sparse winding.
