TPS3809: Thermal Resistance Values

Chad Ricci
Prodigy 70 points
Part Number: TPS3809

I am wondering what the thermal resistance values for part #:TPS3809 are with a unit of measurement of °C/W. The area of interest is junction to case, junction to board, junction to ambient, or whichever information is available. The information is not presented in the datasheet. Thanks!

    Chad,

    I have submitted a request with the thermal modelling team, and I will have this data for you in a few days.

    Thank you for your patience,
    Ricardo
