THERMAL INFORMATION
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.
Three basic approaches for enhancing thermal performance are listed below:
Improving the power dissipation capability of the PCB design
Improving the thermal coupling of the component to the PCB by soldering the ThermalPAD
Introducing airflow in the system
For more details on how to use the thermal parameters, see the application notes: Thermal Characteristics
Application Notes SZZA017 and SPRA953.
