Hi Team, 

Customer would like to know what's the negative impact on thier system design if they selected for example 1.0uH, which is out of recommended range. (2.2uH to 47uH recommended in d/s).
Thank you very much for your support. regards, ny

  • Hi sir,

    It will makes the operation frequency fsw very high and limit the maximum output current capability. Please read the datasheet page 11-12.
