DESCRIPTION
High Efciency USB
Power Manager Plus 1A
Buck-Boost Converter
The LTC
3566 family are highly integrated power manage-
ment and battery charger ICs for Li-Ion/Polymer battery
applications. They include a high efciency current lim-
ited switching PowerPath manager with automatic load
prioritization, a battery charger, an ideal diode, and a high
efciency synchronous buck-boost switching regulator.
Designed specically for USB applications, the LTC3566
family’s switching power manager automatically limits input
current to a maximum of either 100mA or 500mA for USB
applications or 1A for adapter-powered applications.
The LTC3566 family’s switching input stage transmits nearly
all of the 2.5W available from the USB port to the system
load with minimal power wasted as heat. This feature
allows the LTC3566 family to provide more power to the
application and eases the constraint of thermal budgeting in
small spaces. The LTC3566-2 automatically reduces charge
current to maintain a regulated 3.6V VOUT during low bat-
tery conditions; the LTC3566 does not. The synchronous
buck-boost DC/DC can provide up to 1A.
The LTC3566 family is available in a low prole 24-lead
4mm × 4mm QFN surface mount package.
