FAN5404 Fairchild Semiconductor, FAN5404 Datasheet - Page 35

• Manufacturer Part Number: FAN5404
• Description: The FAN5404 combines a highly integrated switched-mode charger, to minimize single-cell Lithium-ion (Li-ion) charging time from a USB power source, and a boost regulator to power a USB peripheral from the battery
• Manufacturer: Fairchild Semiconductor

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