UCC28180: Soft Over Current

Part Number: UCC28180

HI all,

My customer asked me, how long the time from SOC detected to decrease the output voltage.

I know it depends on  the surrounding parts.

But I needs the range,  few ms or 1 sec or..

    Hi Doi-san,
    The soft over current is used to limit the input current and it acts by pulling down on the VCOMP value.
    This has the effect of lowering the output voltage. This happens almost instantaneously : as soon as the limit is reached, the input current is limited and you will see that the output voltage begins to drop.
    I hope this answers your question.

    Regards
    John
