Hi Team,

My customer wants to test UCC28C50 on the UCC25C56EVM. How do I modify the EVM to make sure the work is normal? thanks.

    Hi Rock,

    The key difference between the UCC28C56  and the UCC28C50 is the UVLO threshold. Not knowing more about the input voltage and output power you would like to support, the key component to switch out is Q5:

    The EVM is currently using a 1700V SiC FET and the UCC28C50 would not be able to properly drive it when VDD is between 7.5 and 17.6V. 

    I hope this answers your question.
