November 2, 2010
36 – 75Vdc Input; 3.3 to 5.0Vdc Output; 13 to 20A Output Current
Thermal Considerations (continued)
Figure 21. KNW020A0F Quasi Peak Conducted
Emissions with EN 55022 Class A limits, Figure 20
filter (VIN = VIN,NOM, Io = 0.80 Io,max).
Layout Considerations
Avoid placing copper areas on the outer layer of the
application PCB directly underneath the power
module in the keep out areas shown in the
Recommended Pad Layout figures. Also avoid
placing via interconnects underneath the power
module in these keep out areas.

Location.
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.
EMC Considerations
The KNW series module shall also meet limits of
EN55022 Class A with a recommended single stage
filter, shown in Figure 20. Please contact your
Lineage Power Sales Representative for further
information.
