Figure 6. Recommended PCB Layout (FAN2002)
Therefore, use wide traces for high current paths and place the
input capacitor, the inductor, and the output capacitor as close
as possible to the integrated circuit terminals. In order to mini-
mize voltage stress to the device resulting from ever present
switching spikes, use an input bypass capacitor with low ESR.
Note that the peak amplitude of the switching spikes depends
upon the load current; the higher the load current, the higher the
switching spikes. The resistor divider that sets the output volt-
age should be routed away from the inductor to avoid RF cou-
pling. The ground plane at the bottom side of the PCB acts as
an electromagnetic shield to reduce EMI.

tion note “PCB Grounding System and FAN2001/FAN2011 High
Performance DC-DC Converters” (AN-42036).
