PCB Layout
High-switching frequencies and relatively large peak
currents make PCB layout a very important aspect of
design. Good design minimizes excessive EMI on the
feedback paths and voltage gradients in the ground
plane, both of which can result in instability or regula-
tion errors. Connect the input capacitors as close as
possible to the PV_ and ground. Connect the inductor
and output capacitors as close as possible to the
device and keep the traces short, direct, and wide to
minimize the current loop area.
The OUTS_ feedback connections are sensitive to
inductor magnetic field interference so route these
traces away from the inductors and noisy traces such
as LX_.
Connect GND_ and PGND2 to the ground plane.
Connect the exposed paddle to the ground plane
with multiple vias to help conduct heat away from
the device.
Refer to the MAX16922 evaluation kit for a PCB layout
example.
