The LTC3586-2/LTC3586-3 are highly integrated power management and battery charger ICs for Li-Ion/Polymer battery applications. They include a high efficiency current limited switching PowerPath manager with automatic load prioritization, battery charger, ideal diode, and four synchronous switching regulators (two bucks, one buckboost and one boost). Designed specifically for USB applications, 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.
