THERMAL INFORMATION
Using thermal resistance, junction-to-ambient (R
θ
JA
), maximum power dissipation can be calculated with the
equation:
PD(max)
TJ(max)
TA
RJA
Where T
J(max)
is the maximum allowable junction temperature or 125
°
C.
This limit should then be applied to the internal power dissipation of the TPS9104. The equation for calculating
total internal power dissipation of the TPS9104 is:
PD(max)
x
VI
VX
IX
VI
IQ
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:
Improving the power dissipation capability of the PWB design
Improving the thermal coupling of the component to the PWB
Introducing airflow in the system
