    Hey high speed guy,

    The ThetaJC of the TPS54610MPWREP will be 28.3 °C/W

    Thanks,
    Daniel

    High Speed Guy,

    Just to clarify, that Theta JC of 28.2 C/W is junction to case TOP.  For PowerPAD package it is not a very useful parameter as nearly all the internal heat is dissipated thru the PowerPAD, not the case top.  You can use all of the thermal parameters of the TPS54610 datasheet for the EP device:

    See:

    For a full explanation of the thermal parameters.  Junction to board thermal resistance of 15.1 C/W is likely the parameter you are interested in.
