MAX38640/1/2/3/A/B

Tiny 1.8V - 5.5V Input, 330nA I , 700mA

nanoPower Buck Converter

PCB Layout and Routing

High switching frequencies and large peak currents make PCB layout a very important part of the buck regulator design.

Good design minimizes excessive EMI (Electromagnetic Interference) on the feedback paths and voltage gradients in the

ground plane, to avoid instability and regulation errors. The input capacitor (C ) should be placed as close as possible

to the IC pins IN and GND. Connect the inductor, input capacitor, and output capacitor (C

) as close together as

OUT

possible, and keep their traces short, direct, and wide.

Connect the two GND pins under the IC and directly to the ground of the output capacitor. Keep noisy traces, such as the

LX node, as short as possible. The OUT pin should be connected to the output capacitor and this trace should be routed

away from the main power path between the inductor and C

. The OUT trace should also be routed away from noisy

OUT

traces such as the LX line or other external noise sources. Refer to the MAX3864x evaluation kit for an example PCB

layout and routing scheme.
