PCB Layout Guide

PCB layout is important to achieve good

performance operation for MP6302. Follow

guidelines below and use the EVB board layout

as a reference.

1) Connect the BST pin as close as possible to

the SW node of DCDC converter through a

resistor and a small ceramic capacitor. Try

to avoid interconnect the feedback path.

2) Ensure all feedback connections are short

and direct. Place the feedback resistors and

compensation components as close to the

chip as possible.

3) Keep the connection of the storage

capacitors and STRG pin as short and wide

as possible.
