HI Sreenivasan,

These design parameters can be done. There will need to be a lot of care when selecting components and doing layout. Since the design calls for 726W it would be a choice to use multiple phases. Here is a good reference design that will help implement your design. Also check out the quickstart calculator as it will help speed up some of the basic calculations.

Thanks,

Garrett
