UCC27424-Q1: UCC27424 rising and falling time

Part Number: UCC27424-Q1

Hi support team,

My customer wishes to know what is the min value for the rise time and fall time of UCC27424-Q1. The datasheet only specify the typical and maximum value, could you please check on this? 

Thank you.

Best Regards,

Wei-Hao

    Wei-Hao,

    Thanks for your support and interest in the UCC27424-Q1.

    We typically don't spec the minimum here since the key care-about for this spec is usually the max time, and the minimum rise time can be controlled much easier with an external gate resistor. This parameter is also very specific to the output conditions on the customer board, in this case we have the output load defined by a cap CLoad = 1.8nF. Do you have more details on the application and why the customer cares about this parameter?

    We won't be able to provide a guaranteed time for the minimum but we can provide some expected data. I think if we understand the application better we can provide more useful information.

    Regards,
