LM21212-1: additional Thermal information?

Part Number: LM21212-1
Other Parts Discussed in Thread: TPS82130

Team,

Do we have additional thermal information to share for LM21212-1 PWP like what we document for TPS82130 (see below)?

Thanks in advance!

    AnBer,

    This is an older device, so I doubt that we have the thermal parameters.  I can request them, but it takes usually about 3 weeks.  Do you want me to submit a request?

    AnBer,

    I found the data:

    For Analysis Requests, please add further description

    1) RθJC(top) Junction-to-case (top) thermal resistance in °C/W 2) RθJB Junction-to-board thermal resistance in °C/W

    Result- Theta JA-High K (standard datasheet value)

    26.4*

    Result-Theta JC, top (standard datasheet value)

    18.6*

    Result-Theta JB (standard datasheet value)

    3.9*

    Result- Psi JT (standard datasheet value)

    0.4*

    Result- Psi JB (standard datasheet value)

    3.9*

    Result-Theta JC, bottom (standard datasheet value)

    0.1*
