The LTC®3567 is a highly integrated power management
and battery charger IC for Li-Ion/Polymer battery applications.
It includes a high effi ciency current limited switching
PowerPath manager with automatic load prioritization,
a battery charger, an ideal diode, and a high effi ciency
synchronous buck-boost switching regulator. Designed
specifi cally for USB applications, the LTC3567’s switching
power manager automatically limits input current to
a maximum of either 100mA or 500mA for USB or 1A for
adapter-powered applications.
The LTC3567’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 LTC3567 to provide more power to the application and
eases thermal budgeting constraints in small spaces.
The synchronous buck-boost DC/DC can provide up to
1A output current.
The LTC3567 is available in a low profi le 24-pin (4mm ×
4mm × 0.75mm) QFN surface mount package.
