THERMAL CHARACTERISTICS
To determine the junction temperature on the application
printed circuit board use:
where:
TJ = Junction temperature (°C)
TCASE = Case temperature (°C) measured by customer at top
center of package.
ΨJT = From Table 51
PD = Power dissipation (see Total Power Dissipation on Page 23
for the method to calculate PD)
Values of θJA are provided for package comparison and printed
circuit board design considerations.
θJA can be used for a first
order approximation of TJ by the equation:
where:
TA = Ambient temperature (°C)
Values of θJC are provided for package comparison and printed
circuit board design considerations when an external heat sink
is required.
Values of θJB are provided for package comparison and printed
circuit board design considerations.
In Table 51, airflow measurements comply with JEDEC stan-
dards JESD51-2 and JESD51-6, and the junction-to-board
measurement complies with JESD51-8. The junction-to-case
measurement complies with MIL-STD-883 (Method 1012.1).
All measurements use a 2S2P JEDEC test board.
The LQFP_EP package requires thermal trace squares and ther-
mal vias to an embedded ground plane in the PCB. The paddle
must be connected to ground for proper operation to data sheet
specifications. Refer to JEDEC standard JESD51-5 for more
information.
