THERMAL CONSIDERATIONS
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.
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 PWB and is vertically positioned within the wind
tunnel. The space between the neighboring PWB and
the 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 should always be
operated below the maximum operating temperature. If
the temperature exceeds the maximum module
temperature, reliability of the unit may be af fected.

Note: C2 & C3 can be 0.01μF to 0.1μF. Select the voltage rating to meet input-to-output isolation requirements. C1 should be the recommended value
suggested in the power module data sheet.

Figure 12 shows the experimental result obtained by using this filter module, together with the recommended external
components shown in Figures 7 and 8. The Q48SB12025NR A module is one of the Delphi series quarter brick 12V, 25A
DCDC converters. Measured noise is greatly dependent on layout, grounding, cable orientation, and load characteristics
and the variation is possible from variou s application conditions.

Note: Inside this filter module, the components have no
voltage polarity. Hence, the input positive (Vin+) and input
negative (Vin-) labels could be swaped for the
convenience of layout and matching with power module
input connected to the filter module, just remember to
swap the output labels accordingly as well. Please refer to
Figures 8 and 10 for how it is applied.
