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.

SLVS451D–SEPTEMBER 2003–REVISED FEBRUARY 2006
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
Introducing airflow in the system

dissipation is about 820 mW. More power can be dissipated if the maximum ambient temperature of the
application is lower.
