Figure 7. PCB Layout Guide

The feedback trace is on bottom layer and

shielded by GND plane of inner layer.

Input capacitors must be placed as

close to IC VIN-GND as possible

GND

SDA

SCL

SW should be connected to inductor by wide and short trace.

Keep sensitive components away from this trace .

Keep analog components away from the BOOT

nodes.

Add 12 thermal vias with 0.25mm diameter on

exposed pad for thermal dissipation and current

carrying capacity. Suggest inner layers are GND

plane.

Extend the GND plane for better thermal

dissipation.

Keep digital signal away from the noise traces and shielded by GND

plane.

Four-layer or six-layer PCB with maximum ground plane

is strongly recommended for good thermal performance.
