HEATSINKING LLP PACKAGE PARTS
The value of θ
for the LLP package is specifically dependent
JA
on PCB trace area, trace material, and the number of layers
and thermal vias. It is recommended that a minimum of 6
thermal vias be placed under the center pad to improve ther-
mal performance.
For techniques for improving the thermal resistance and pow-
er dissipation for the LLP package, please refer to Application
Note AN-1187.
