    Hi Alpha,

    I apologies for delayed response.

    No, this won't work with TPS22811. Similar to TPS259814, dvdt will gets internally shorted to Vout after the startup is finished. That will cause Vgs of external FET to go to 0V. 

    In TPS259813, we don't have this shorting so only that variant can be used to drive external FET.

    Best Regards,
    Arush
