CIRCUIT BOARD LAYOUT RECOMMENDATIONS
Good circuit board layout is essential to obtain the best
performance from the ADP2300/ADP2301. Poor layout can
affect the regulation and stability, as well as the electromagnetic
interface (EMI) and electromagnetic compatibility (EMC)
performance. A PCB layout example is shown in Figure 50.
Refer to the following guidelines for a good PCB layout:
•
•
•
•
Place the input capacitor, inductor, catch diode, output
capacitor, and bootstrap capacitor close to the IC using
short traces.
Ensure that the high current loop traces are as short and wide
as possible. The high current path is shown in Figure 49.
Maximize the size of ground metal on the component side
to improve thermal dissipation.
Use a ground plane with several vias connecting to the
component side ground to further reduce noise inter-
ference on sensitive circuit nodes.

INPUT CA P
Minimize the length of the FB trace connecting the top of the
feedback resistive voltage divider to the output. In addition,
keep these traces away from the high current traces and the
switch node to avoid noise pickup.
