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

CHIP SCALE PACKAGE DIMENSIONS
The TPS6230x, TPS6231x, and TPS6232x are also available in an 8-bump chip scale package (YZD,
NanoFree and YED, NanoStar). The package dimensions are given as:
D = 1.970

SLVS528B–JULY 2004–REVISED JUNE 2005
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 (T
J
) of the TPS6230x, TPS6231x, and TPS6232x devices is
125

C. The thermal resistance of the 8-pin CSP package (YZD and YED) is R

JA
= 250

C/W. Specified regulator
operation is assured to a maximum ambient temperature T
of 85
°
C. Therefore, the maximum power dissipation
is about 160 mW. More power can be dissipated if the maximum ambient temperature of the application is lower
or if the PowerPAD package (DRC) is used.
