    Hello Doi-san
    The UCC28180 has output overvoltage protection (OVP), open loop protection (OLP), ISENSE open pin protection (ISOP), ICOMP open pin protection (ICOMPP) and VCC undervoltage protection (UVLO) .
    There is also a peak current limit (PCL) and a soft over current limit (SOC)
    All of these limit parameters are detailed in the data sheet.
    Startup behaviour and recovery from a transient is influenced by the enhanced dynamic response (EDR) of the error amplifier. This gives a fast and controlled recovery to the regulation set point. There is no soft start pin function on the UCC28180.
    Hope this is all of the information you require.
    Regards
    John

    Hi John-san,

    I think the customer want is waveform transit timing chart.

    Not description document.

    Such like UCC28064A  Data Sheet Figure 27. , UCC28950 Data Sheet Figure 1.
