The LTC®3567 is a highly integrated power managementand battery charger IC for Li-Ion/Polymer battery applicaTIons.It includes a high effi ciency current limited switchingPowerPath manager with automaTIc load prioriTIzaTIon,a battery charger, an ideal diode, and a high effi ciencysynchronous buck-boost switching regulator. Designedspecifi cally for USB applications, the LTC3567’s switchingpower manager automatically limits input current toa maximum of either 100mA or 500mA for USB or 1A foradapter-powered applications.The LTC3567’s switching input stage transmits nearly all ofthe 2.5W available from the USB port to the system loadwith minimal power wasted as heat. This feature allowsthe LTC3567 to provide more power to the application andeases thermal budgeting constraints in small spaces.The synchronous buck-boost DC/DC can provide up to1A output current.The LTC3567 is available in a low profi le 24-pin (4mm ×4mm × 0.75mm) QFN surface mount package.
