LTC3567EUF-TRPBF

FEATURES LTC3567 High Efficiency USB Power Manager Plus 1A Buck-Boost Converter with I2C Control DESCRIPTION The LTC®3567 is a highly integrated power management and battery charger IC for Li-Ion/Polymer battery applications. It includes a high efficiency current limited switching PowerPath manager with automatic load prioritization, a battery charger, an ideal diode, and a high efficiency synchronous buck-boost switching regulator. Designed specifically 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 profile 24-pin (4mm × 4mm × 0.75mm) QFN surface mount package. L, LT, LTC and LTM are registered trademarks of Linear Technology Corporation.
