Hello-

What is the maximum power dissipation of the TPS7A8101 at 70 degrees C, as a function of airflow?

Thanks and Best Regards

Hi Tim,

We do not typically do this level of thermal characterization. An estimation can be made by using the junction to board thermal metric provided in the datasheet if you are able to relate the board temperature to your air flow.

Very Respectfully,
Ryan

WEBENCH® Designer includes WEBTHERM Simulations tool that includes the TPS7A8101.

A feature of the WEBTHEM allows you to vary the airflow rate and airflow direction across the device mounted to a pre-defined PCB.
