Thermal Considerations
Power modules operate in a variety of thermal
environments; however, sufficient cooling should always
be provided to help ensure reliable operation.
Considerations include ambient temperature, airflow,
module power dissipation, and the need for increased
reliability. A reduction in the operating temperature of the
module will result in an increase in reliability. The thermal
data presented here is based on physical measurements
taken in a wind tunnel. The test set-up is shown in Figure
34. Note that the airflow is parallel to the short axis of the
module as shown in figure 33. The derating data applies
to airflow in either direction of the module’s short axis.
Figure 33. T ref Temperature measurement location.
The thermal reference point, T
specifications is shown in Figure 33. For reliable
operation this temperature should not exceed 115
The output power of the module should not exceed the
rated power of the module (Vo,set x Io,max).

thermal aspects including maximum device temperatures.
Heat Transfer via Convection
Increased airflow over the module enhances the heat
transfer via convection. Thermal derating curves showing
the maximum output current that can be delivered at
different local ambient temperatures (T
conditions ranging from natural convection and up to
2m/s (400 ft./min) are shown in the Characteristics
Curves section.
Layout Considerations
Copper paths must not be routed beneath the power
module. For additional layout guide-lines, refer to the
FLTR100V10 application note.
