the module has reached thermal equilibrium. If
a heat sink is mounted to the case, make the
measurement as close as possible to the indi-
cated position. It makes the assumption that the
final system configuration exists and can be
used for a test environment.
The following text and graphs show guidelines
to predict the thermal performance of the mod-
ule for typical configurations that include heat
sinks in natural or forced airflow environments.
Note that Tc of module must always be checked
in the final system configuration to verify proper
operational due to the variation in test condi-
tions.
Thermal management acts to transfer the heat
dissipated by the module to the surrounding
environment. The amount of power dissipated
by the module as heat (P
tion below:
Also, module efficiency (η) is defined as the fol-
lowing equation:
If eliminating the input power term, from two
above equations can yield the equation below:
The module power dissipation then can be cal-
culated through the equation.
Because each power module output voltage
has a different power dissipation curve, a plot of
power dissipation versus output current over
three different line voltages is given in each-
module-specific data sheet. The typical power
dissipation curve of AV60C-30W series 3.3V
and 5V output are shown as figure 23 to figure
24.

Experiment Setup
From the experimental set up shown in figure
25, the derating curves as figure 26 can be
drawn. Note that the PWB ( printed-wiring
board ) and the module must be mounted verti-
cally. The passage has a rectangular cross-
section. The clearance between the facing
PWB and the top of the module is kept 13 mm
(0.5 in.) constantly.
