Implementation of integrated circuits in low-profile and fine-pitch surface-mount packages typically requires special attention to power dissipation. Many system-dependent issues such as thermal coupling, airflow, added heat sinks and convection surfaces, and the presence of other heat-generating components affect the power dissipation limits of a given component.

Two basic approaches for enhancing thermal performance are:

• Improving the power dissipation capability of the PCB design
• Introducing airflow in the system

The Thermal Data section in Thermal Information provides the thermal metric of the device on the EVM after considering the PCB design of real applications. The big copper planes connecting to the pads of the IC on the PCB improve the thermal performance of the device. For more details on how to use the thermal parameters, see Thermal Characteristics of Linear and Logic Packages Using JEDEC PCB Designs application note and Semiconductor and IC Package Thermal Metrics application note.
