PCB LAYOUT GUIDELINES

Poor layout can affect ADP5022 performance, causing electro-

magnetic interference (EMI) and electromagnetic compatibility

(EMC) problems, ground bounce, and voltage losses. Poor

layout can also affect regulation and stability. A good layout is

implemented using the following guidelines:

•

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 as 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.
