11.2.1 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.

Section 7.4 provides the thermal metric of the device on the TPS62097 EVM after considering the PCB design of real applications. The big copper planes connecting to the pads of the IC on the PCB board improve the thermal performance of the device. For more details on how to use the thermal parameters, see the application notes: Thermal Characteristics Application Notes SZZA017 and SPRA953.
