PCB Layout and Routing
High switching frequencies and relatively large peak
currents make the PCB layout a very important aspect
of design. Good design minimizes excessive EMI on the
voltage gradients in the ground plane that can result in
instability or regulation errors. Connect the input and out-
put capacitors as close as possible to the IC. Connect
the inductor as close as possible to the IC and keep the
traces short, direct, and wide. Connect AGND to the
exposed pad directly under the IC. Connect AGND and
PGND to the ground plane. Keep noisy traces, such as
the LX node, as short as possible.
USB Hi-Speed requires careful PCB layout with 45ω
controlled-impedance matched traces of equal lengths.
Ensure that bypass capacitors are as close as possible
to the IC. Use large ground planes where possible.
Refer to the MAX8893 evaluation kit for an example PCB
layout design.
