TPS54116-Q1: Power up / down sequence

Part Number: TPS54116-Q1

Hi team,

I have  question about the power up down sequence of TPS54116-Q1. 

Is there any restrictions in power up / down order and timing for PVIN/AVIN/VLDOIN? 

Do you have a verification report for the power up/down sequence test?

regards,

  • Hi Shinji,

    Sorry for the late reply. Just notice this post.
    In typical application, PVIN and AVIN are connected to the same input voltage.
    VLDOIN is is connected to the VDDQ.

    During power on, it is suggested to pull ENSW and ENLDO low before applying input voltage.
    During power off, pull ENSW and ENLDO low and then power down input voltage.

    Thanks
    Qian
