    Thread Summary
    
                The user inquired about a PSFB controller solution for a 2kW step-up converter (48Vdc to 600Vdc) with bidirectional support. The support engineer confirmed that the selected controllers (LTC1922, LTC3722, ADP1046A + microcontroller) are not designed for bidirectional operation. The engineer suggested the non-isolated bidirectional LTC7871 demo board (DC2886A) and the LTC3871 demo design (DC2348) as potential solutions, which could be extended to 6 phases.

    Hi,
    

    I am looking at PSFB controller solution for 2KW (48Vdc to 600Vdc, step-up).
    

    If there is a solution with bidirectional support I am happy (or) I need boost implementation.
    

    Input voltage: 48Vdc
    

    Output voltage: 600Vdc
    

    Output power: 2KW
    

    Some of the controllers selected and not sure whether it can be used for the above specification or not.
    

    Selected controllers
    

    LTC1922
    

    LTC3722
    

    ADP1046A + microcontroller
    

    Please suggest if any other better part will meet the requirement.
    

    Thanks,
    

    Sakthivishnu
