    Hello Avinash,

    Welcome to the Forum!

    A detailed answer to that question is beyond what can be posted in this forum.  There are however various app notes available on each of those circuits.  A general search of the web will also provide you with multiple sources of information from which you can get a better understanding of each design.

    Once you have an idea of what you are looking for and which topology best suits your needs, then you can come back and ask about the different devices available for building your circuit.

    Here is a starting point http://www.ti.com/lit/sg/sluw001e/sluw001e.pdf.

    Thanks,

    The things that come to mind are efficiency, performance, parts count, input and output isolation, the ability to perform booth buck and boost, ripple current reduction, continuous current mode, less stress on components are just a few reasons.  You can find out a lot more by looking at tutorials on all of them on the web.

    Thanks,
