PMP6712: Seeking more help for slua81-PMP6712 ​​reference design

Hello.

    sluua81-PMP6712.pdf

     I need to design a DC / DC power supply with a rated 48V, an input voltage of 38V ~ 58V, and an output of 50V / 20A / 1000W.

     I want to refer to the PMP6712 ​​design case you provided. In this case, the DC / DC power supply specifications are 38V ~ 60V, and the output is 54V / 15A / 810W.

     Your reference cases have helped me a lot.

     Due to the urgency of the boss in this case, I have not done a similar circuit before, and it takes a certain time to learn to digest and then make a prototype. I wonder if I can ask for more help:

     1. Whether a 50V / 20A / 1000W development board can be customized, the cost can be negotiated.

     2. How can I buy the PMP6712 ​​development board if it cannot be customized?

     3. If the PMP6712 ​​development board cannot be purchased, I change the design by myself. What parameters do I need to change?

     4. Can you provide a more detailed calculation design book and simulation model for the design case? I found other calculation and simulation cases based on UCC28950 on the official website, but no PMP6712 ​​calculation and simulation data.

     The PMP6712 ​​design case you provided has helped me a lot, but the development time of this case is too urgent. If you can give more support, it will better promote the development and production of this product.

     Thank you!

    Dear Sir,

    1) for a customized design please contact your local Texas Instruments field contact;
    if biz case is promising and probability of win seems good TI could consider a custom design.
    But our workload needs to be justified by biz case.

    2) we are not selling any reference designs; these are no EVMs.

    3) for bigger output power the power stage needs to get bigger, too - especially transformer and inductor.
    but PMP6712 is capable of 48V/35A 1.7kW by using two interleaved power stages.

    4) please download TI Power Stage Designer ver4 to work on 3) and get familiar w/ topology;
    typically you won't find any simulation data for our designs; we're just calculating and building them.

    It will be very hard to build a 1kW full bridge converter w/out any experience in power electronics;
    furthermore for a new ground up design I would use UCC28951.

    Best regards, Bernd
