Thermal Considerations (continued)

Figure 19. Trefx Temperature Measurement

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.

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.
