  • RE: UCC12050: Design for soft start.

    Resolved
    Hi, Kengo, I powered on the EVM by turning on Vin and EN simultaneously, the peak input current is 0.22A, well below what you saw. Please re-measure the waveform, and make sure the scope scale is right. The inrush is input current, not output current…
