The LTC®3586-2/LTC3586-3 are highly integrated power
management and battery charger ICs for Li-Ion/Polymer
battery applications. They include a high efficiency cur-
rent limited switching PowerPath manager with automatic
load prioritization, battery charger, ideal diode, and four
synchronous switching regulators (two bucks, one buck-
boost and one boost). Designed specifically for USB ap-
plications, the LTC3586-2/LTC3586-3’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.
Unlike linear chargers, the LTC3586-2/LTC3586-3 switching
architecture transmits nearly all of the power available from
the USB port to the load with minimal loss and heat which
eases thermal constraints in small places. The two buck
regulators can provide up to 400mA each, the buck-boost
can deliver 1A, and the boost delivers at least 800mA.
The LTC3586-2/LTC3586-3 are available in a low profile
(0.75mm) 38-pin 4mm × 6mm QFN package.
