PCB Layout Recommendations

Bypass capacitors should be placed as close to the IC as

possible. In particular, the total loop length for CMID should

be minimized to reduce overshoot and ringing on the SW,

PMID, and VBUS pins. All power and ground pins must be

routed to their bypass capacitors, using top copper whenever

possible. Copper area connecting to the IC should be

maximized to improve thermal performance if possible.
