Figure 36. TPS6110x EVM Circuit Diagram
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.
Introducing airflow in the system.
The maximum junction temperature (T
J
) of the TPS6110x devices is 150
°
C. The thermal resistance of the 20-pin
TSSOP package (PW) isR
Θ
JA
= 155 K/W (QFN package, RGE, 161 K/W). Specified regulator operation is
assured to a maximum ambient temperature T
A
of 85
°
C. Therefore, the maximum power dissipation is about 420
mW. More power can be dissipated if the maximum ambient temperature of the application is lower.
