CIRCUIT BOARD LAYOUT RECOMMENDATIONS
ADP2300/ADP2301
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.
?
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.
Refer to the following guidelines for a good PCB layout:
VIN
BST
?
Place the input capacitor, inductor, catch diode, output
capacitor, and bootstrap capacitor close to the IC using
ADP2300/
ADP2301 SW

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
Figure 49. Typical Application Circuit with High Current Traces Shown in Blue
