9.3 PCB Layout Guidelines
The high-speed operation of the AS1322 requires proper layout for optimum performance. Figure 23 shows the recommended component
layout.
A large ground pin copper area will help to lower the device temperature.
A multi-layer board with a separate ground plane is recommended.
Traces carrying large currents should be direct.
Trace area at pin FB should be as small as is practical.
The lead-length to the battery should be as short as is practical.
