PCB LAYOUT GUIDELINES
Poor layout can affect ADP2503/ADP2504 performance, caus-
ing electromagnetic interference (EMI) and electromagnetic
compatibility (EMC) performance, ground bounce, and voltage
losses. Poor layout can also affect regulation and stability. A good
layout is implemented using the following rules:
•
Place the inductor, input capacitor, and output capacitor
close to the IC using short tracks. These components carry
high switching frequencies and large tracks act like antennas.

•
•
•
Route the output voltage path away from the inductor and
SW node to minimize noise and magnetic interference.
Maximize the size of ground metal on the component side
to help with thermal dissipation.
Use a ground plane with several vias connecting to the
component side ground to further reduce noise interference
on sensitive circuit nodes.
