PCB LAYOUT GUIDELINES
Poor layout can affect ADP5041 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.
SUGGESTED LAYOUT
See Figure 114 for an example layout.
