Figure 21. Thermocouple Placement for Temperature Derating Calculations
Figure 20 readily allows users to confirm that DATEL quarter-brick DC/DC converters are compatible to the industry-standard pinout, independent of pin-numbering conventions.
The typical derating curves on the previous pages were developed by moni- toring the temperature of the case with a thermocouple placed on top of the USQ case as shown in Figure 21. Users desiring to model their own application's temperature derating for a particular environment (enclosed area, orientation, airflow, possible heatsinking) should make sure the case temperature does not exceed 110°C for any condition.
