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

possible. Copper area connecting to the IC should be
maximized to improve thermal performance.
