3 thermal consideratio ns thermal management is an important part of the system design. to ensure proper, reliable operation, sufficient cooling of the power module is needed over the entire temperature range of the module. convection cooling is usually the dominant mode of heat transfer. hence, the choice of equipment to characterize the thermal performance of the power module is a wind tunnel. the rmal testing setup deltas top of the power module is 6.35mm (0.25). thermal derating heat can be removed by increasing airflow over the module. figure 4 show s maximum output is a function of ambient temperature and airflow rate. to enhance system reliability, the power module sh ould always be operated below the maximum operating temperature. if the temperature exceeds the maximum module temperature, reliability of the unit may be affected. figure 4 : win d tunnel test setup figure dimensions are in millimeter s and (inches) . thermal curves figure 5 : temperature measurement location the allowed maximum hot spot temperature is defined at 110 figure 6 : output current vs. ambient temperature and air velocity @ vin = 48v (either orientation) note: wind tunnel test setup figure dimensions are in millimeters and (inches) 10 (0.4) module air flow 50.8 (2.0) facing pwb pwb air velocity and ambient te mperature measured below the module out gnd FL75L10 (standard) output current vs. ambient temperature and air velocity @ vin = 48v (either orientation) 0 2 4 6 8 10 12 50 55 60 65 70 75 80 85 ambient temperature ( ) output current(a) natural convection 100lfm
