Thermal Information
Implementation of integrated circuits in low-profile and fine-pitch surface-mount packages typically requires
special attention to power dissipation. Many system-dependant 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
Introducing airflow in the system
The maximum recommended junction temperature (TJ) of the TPS6265x device is 105°C. The thermal resistance
of the 9-pin CSP package (YFF) is RθJA = 105°C/W. The regulator operation is specified to a maximum ambient
temperature TA of 85°C. Therefore, the maximum power dissipation is about 200mW.
