Thermal Design
The thermal data can be used to determine thermal performance
without a heatsink.
Case temperature is calculated by the following formula:
TC = TA + Pd x RthC-A where Pd = PO(1/
η - 1)
Where:
TC: Case Temperature
TA: Local Ambient Temperature
Pd: Dissipated Power
RthC-A: Thermal Resistance from TC to TA
The efficiency
η can be found in the tables on the following
pages.
For design margin and to enhance system reliability, it is
recommended that the PKJ 4000B series DC/DC power modules
be operated at case temperatures below 90°C.
