10 / 14 page Advance Data Sheet November 17, 2011 40A Analog Mega DLynxTM: Non-isolated DC-DC Power Module 4.5 – 14.4Vdc input; 0.6Vdc to 2Vdc output; 40A output current LINEAGE POWER 10 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 8. The preferred airflow direction for the module is in Figure 9. Air flow x Power Module Wind Tunnel PWBs 12.7_ (0.50) 76.2_ (3.0) Probe Location for measuring airflow and ambient temperature 25.4_ (1.0) Figure 8. Thermal Test Setup. The thermal reference points, Tref used in the specifications are also shown in Figure 9. For reliable operation the temperatures at these points should not exceed 120 oC. The output power of the module should not exceed the rated power of the module (Vo,set x Io,max). Please refer to the Application Note “Thermal Characterization Process For Open-Frame Board- Mounted Power Modules” for a detailed discussion of thermal aspects including maximum device temperatures. Figure 9. Preferred airflow direction and location of hot-spot of the module (Tref). |
