Hi every body
I want to design a switching power that has 15V,DC and 1ADC out put, and in put is 220V, AC and frequency is 50 Hz, any schematic and pdf is so appreciated, mean while is there any software that can design this power for me ?
Dear mf1364
Hi
I can suggest you these two famous and terrific books: switching power supply design by abraham pressman and switching power supply cookbook by marty brown.

At such low power, you can consider integrated devices which integrate the control with the power device (MOSFET). You can use the TOP-Switch series from Power Integrations or the VIPer series from ST Microelectronics or similar devices from other manufacturers such as Fairchild, IR, etc
For design software, check the websites of the manufacturer. Power Integrations has a software - PIExpert. ST has a similar software and I'm sure all manufacturers should include some sort of software.
You can also make a power supply using a controller such as UC384x and MOSFET.
Two good books have already been recommended to you. I would also recommend them. Plus, you should study the related application notes of the manufacturers.
Don't blindly follow the software. Try to understand how the software works out the solution.
