    There is no special timing requirement of TPS53622.

    Please check the recommended sequence in datasheet section 7.

    The recommended power-up sequence is:

    1. 3.3 V

    2. 5 V

    3. PS_EN

    4. 12 V

    5. VR_EN

    The recommended power-down sequence is:

    1. VR_EN

    2. 12 V

    3. PS_EN

    4. 5 V

    5. 3.3 V

    Thanks
