Evaluation Board Description
The SKY65338 Evaluation Board is used to test the performance
of the SKY65338 FEM. The Evaluation Board schematic diagram
is shown in Figure 6. An assembly drawing for the Evaluation
Board is shown in Figure 7 and the layer detail is provided in
Figure 8. The layer detail physical characteristics are noted in
Figure 9. Table 6 provides the Bill of Materials (BOM) list for
Evaluation Board components.
Circuit Design Considerations
The following design considerations are general in nature and
must be followed regadless of final use or configuration:
1. Paths to ground should be made as short as possible.
2. The ground pad of the SKY65338 has special electrical and

thermal grounding requirements. This pad is the main thermal
conduit for heat dissipation. Since the circuit board acts as
the heat sink, it must shunt as much heat as possible from
the device. Therefore, design the connection to the ground
pad to dissipate the maximum wattage produced by the
circuit board. Multiple vias to the grounding layer are
required.
