TPS3809: Thermal Resistance Values

Chad Ricci

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

Chad,

Below are the results from the thermal model team's analysis.

Thermal Resistance	°C/W
Result- Theta JA-High K (standard datasheet value):	255.4
Result-Theta JC, top (standard datasheet value):	155.4
Result-Theta JB (standard datasheet value):	131.7
Result- Psi JT (standard datasheet value):	51.8
Result- Psi JB (standard datasheet value):	130.6
Result-Theta JC, bottom (standard datasheet value):	n/a
