Dears,

TPS630701 is used in the customer's project, and when this material is powered on again, the instantaneous current reaches 1.2A, if this value can be reduced through some modifications，tks！

    Hi   

    Do you mean the inrush current during start up is 1.2A?  and you want to decrease this current?

    Do you have some waveforms to help me to understand your question better?

    Regards

    Yes,

     Customer wants to know what is the mathematical relationship between soft start and power on impulse current? How to change the impact current at the moment of power on by adjusting the soft start time?

    Hi,

    Mostly,  we can not build a mathematical model between Tss and inrush current.

    unfortunatly, the Tss is build internal totally and we are not able to change it by external components.

    Do you have a more clear waveform about the inrush current, it is better you can help to capture the inrush current and switching node together.

    Regards
