    Hello Adarsh 

    LM5116 is rated up to 100V, but the 100V is an absolute maximum rating and practically there is no margin if you run at 100V. Also, you have to stack up more than 6-phases in parallel using external circuity, which is complex. Usually, external drivers / power stages are used for such a high voltage and the high power (~1kW) system. You can use external driver with non-isolated DC/DC controller. And also an isolated topology is good since single phase design is possible. Please refer the 12V output 1kW reference design https://www.ti.com/lit/ug/tidt334/tidt334.pdf and if you have a question about this reference design, please create a new post.
