    Hi Ann,

    We have a 5V/50A apps circuit in the datasheet that could be adjusted for 12V/67A. However, I recommend using 3 or 4 phases, depending on max ambient temperature, as 33A/phase is a bit high with just 2 phases. Please fill out the LM5143 quickstart calculator and send me the file for review.

    Regards,

    Tim
