Total Power Solution for Portable Applications General Description The AAT2550 is a fully integrated total power solution with two step-down converters plus a singlecell lithium-ion / polymer battery charger. The stepdown converter input voltage range spans 2.7V to 5.5V, making the AAT2550 ideal for systems powered by single-cell lithium-ion/polymer batteries. The battery charger is a complete constant current/ constant voltage linear charger. It offers an integrated pass device, reverse blocking protection, high current accuracy and voltage regulation, charge status, and charge termination. The charging current is programmable via external resistor from 100mA to 1A. In addition to these standard features, the device offers over-voltage, over-current, and thermal protection.
