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. THERMAL CURVES OUT GND OUT (0.6in) 15mm Natural Convection 3 Thermal Testing Setup Delta’s filter modules are characterized in heated vertical wind tunnels that simulate the thermal environments encountered in most electronics equipment. This type of equipment commonly uses vertically mounted circuit cards in cabinet racks in which the power modules are mounted. The following figure shows the wind tunnel characterization setup. The filter module is mounted on a test PW B and is vertically positioned within the wind tunnel. The space between the neighboring PW B and the top of the power module is 6.35mm (0.25”). 7mm (0.275in) Figure 5: Temperature measurement location The allowed maximum hot spot temperature is defined at 120℃ Output Current(A) 6 FL75L05 (Standard) Output Current vs. Ambient Temperature and Air Velocity @ Vin = 48V (Either orientation) 5 Thermal Derating Heat can be removed by increasing airflow over the module. Figure 4 shows maximum output is a function of ambient temperature and airflow rate. To enhance system reliability, the power module should always be operated below the maximum operating temperature. If the temperature exceeds the maximum module temperature, reliability of the unit may be affected. 4 100LFM 2 1 0 50 55 60 65 70 75 80 85 Ambient Temperature (℃) FACING PW B PW B MODULE Figure 6: Output Current vs. Ambient Temperature and Air Velocity @ Vin = 48V (Either Orientation) AIR VELOCITY AND AMBIENT TEMPERATURE MEASURED BELOW THE MODULE AIR FLOW 50.8 (2.0”) 10 (0.4”) Note: Wind Tunnel Test Setup Figure Dimensions are in millimeters and (Inches) Figure 4: Wind tunnel test setup figure dimensions are in millimeters and (inches). 3 APPLICATION Note: C2 through C5 can be 0.01μF to o.1μF. Select the voltage rating to meet input-to-output isolation requirements. C1 should be the recommended value indicated in the power module data sheet. Figure 7. Recommended schematic when used as the input filter to a high-frequency dc-to-dc converter Note: Vdc input(+) and Vdc input(-) planes should overlay each other, as should the Vi(+) and Vi(-) planes, as should the Vout(+) and Vout(-) planes. Avoid routing signals or planes under the power module or the filter module. Ensure all connections are low impedance. Figure 8.

The Q48SR3R335NR module is one of the Delphi series quarter brick 3.3V, 35A DCDC converters. Measured noise is greatly dependent on layout, grounding, cable orientation, and load characteristics and the variation is possible from various application conditions. Figure 10.
