Hello Piyush

This tool will give you a schematic, component selection and various other outputs to help you design your project.

There is a lot of background information too about Flybacks in general - for example

I wants to know how to design flyback converter (and every other converter)from start to end.

There are good design in webench tool. But I don't know how to design them and what to consider while designing them.

Hello Piyush

There is a lot of good basic information available on the Web.

The Power Supply Design Seminar series from TI is a very good place to start, it's at http://www.ti.com/ww/en/power-training/login.shtml if you enter 'flyback' into the keywords field you will see links to about 12 detailed articles, including the two linked here I'd suggest you start with the one at https://www.ti.com/seclit/ml/slup261/slup261.pdf If you are interested in the EMI performance, I'd reccomend the article at https://www.ti.com/seclit/ml/slup338/slup338.pdf

would also be a worthwhile investment.

Please let me know if you need any further information.

Regards

Colin
