Application Hints
POWER DISSIPATION AND DEVICE OPERATION
The permissible power dissipation for any package is a
measure of the capability of the device to pass heat from the
power source, the junctions of the IC, to the ultimate heat
sink, the ambient environment. Thus, the power dissipation
is dependant on the ambient temperature and the thermal
resistance across the various interfaces between the die and
ambient air.
As stated in notes 3 and 5 in the electrical specifications
sections, the allowable power dissipation for the device in a
given package can be calculated using the equation:
With a
θ
JA
= 50C/W, the device in theLLP package returns
a value of 2.0W with a maximum junction temperature of
