    Hi Hiro,
    

    Please check page 18 of datasheet. It list theta-JA values. All based on the actual PCB implementation using demo board. I'm not sure if we have other info that this. Please connect to local ADI sales team if you need the other data.
    

    Refer to LTM4637 datasheet page 16 for more detailed information about thermal considerations.
