EMC Test Conditions See Figure11. Thermal Considerations The converter is designed to operate in different thermal environments and sufficient cooling must be provided. Proper cooling of the DC-DC converter can be verified by measuring the temperature at the test points as shown in Figure 16 and Figure 17. The temperature at these points should not exceed the maximum values in Table 1 when the module is operating. For a typical application, forced airflow direction is from Vin- to Vin+. Figure 18 shows the derating of output current vs. ambient air temperature at different air velocity.
