    Hi TS,

    Does TPS51200 provide VTT power for DDR in this application?
    If it is DDR application, TPS51200 REFOUT pin should be connected to DDD REF pin directly. A 0.1uF cap is suggested between REFOUT pin and GND.

    I see there is a lot of components connected to TPS51200 REFOUT pin, I don't the purpose of these components. Can you double check it.
    Other than that, the schematic looks fine.

    In layout, place at lease one pcs of 10uF cap close to TPS51200 VO pin.

    Thanks
    Qian
