100W DC-DC solution

Hi Leonard：
   I designed with Webench，there are only 8 solutions, they are UCC25630X+UCC24624.

   In fact, the target design product is railway DC-DC power,  Whether TI has a successful case in railway DC-DC? 

   In my first post, I also gave the main IC information of other railway DC-DC products, which used NE555 and another TI device, so I think there should be more than one solution, please help to suggest.

   The picture below is the basic parameters I used to find railway DC-DC on the market: 

 Thanks!

Eric,

I consulted with our Power Design Services.  With over 10,000 designs, they do not have one that meets those requirements.  100 W from a half brick should not pose any significant problems.  With regard to your IC information of other railway DC-DC products, which used NE555 and another TI device, NE555 is just a timer.  It will not be possible to derive any clues to the design from it.  Can you share one of your Webench designs or the precise inputs you used?

Eric,

Do you have any further questions?

Hi John:

    The DC-DC module need Isolation, so my Webench design as below:

    Only 8 selection, and all are UCC25630X, so whether TI only recommends this solution, thanks!

Eric,

That seems reasonable.  Just to be clear, our group does not support anything with that high of an input voltage.

Hi John:

   No more question, thanks!
