    Hello Fandy,

    Datasheet has a footnote (copied below) that explains how to interpret absolute maximum ratings. Basically, operation beyond the conditions listed in the "recommended operating conditions" section is not recommended. This is not specific to TPS65651 and is similar for most other TI devices.

    Kind Regards,
    Liaqat


    (1) Stresses beyond those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings
    only, and functional operation of the device at these or any other conditions beyond those indicated under recommended operating
    conditions is not implied. Exposure to absolute-maximum-rated conditions for extended periods my affect device reliability.
