7.2 Convection Requirements for Cooling
To predict the ap proximate cooling needed for the module, refer to the
Power De-rating curves in Figures 8 to 10 . These de-rating curves are
approximations of the ambient temperatures and airflows required to
keep the power module temperature below its maximum rating. Once the
module is assembled in the actual system, the module’s temperature
should be checked as shown in Figure 6 to ensure it does not exceed
110°C.
Proper cooling can be verified by measuring the power module’s
temperature at Q1-pin 6 and Q2-pin 6 as shown in Figure 7.

7.3 Thermal Considerations
The power module operates in a variety of thermal
however, sufficient cooling should be provided to help ensure reliable
operation of the unit. Heat is removed by conduction, convection, and
radiation to the surrounding environment. The thermal data presented is
based on measurements taken in a set-up as shown in Figure 6. Figures
8 to 10 represent the test data. Note that the airflow is parallel to the long
axis of the module as shown in Figure 6 for the VPOL15A-5-SIP.
The temperature at either location should not exceed 110 °C. The output
power of the module should not exceed the rated power for the module
(VO, set x IO, max). The SMT15 thermal data presented is based on
measurements taken in a wind tunnel. The test setup shown in Fig 6 and
EUT need to solder on 33mm x 40.38mm(1.300'' x 1.59'') test pcb. Note
that airflow is parallel to the long axis of the module as shown in Fig 6.
