Total Power Solution for Portable Applications

General Description

The AAT2550 is a fully integrated total power solu-

tion with two step-down converters plus a single-

cell lithium-ion / polymer battery charger. The step-

down converter input voltage range spans 2.7V to

5.5V, making the AAT2550 ideal for systems pow-

ered by single-cell lithium-ion/polymer batteries.

The battery charger is a complete constant current/

constant voltage linear charger. It offers an inte-

grated pass device, reverse blocking protection,

high current accuracy and voltage regulation,

charge status, and charge termination. The charg-

ing current is programmable via external resistor

from 100mA to 1A. In addition to these standard

features, the device offers over-voltage, over-cur-

rent, and thermal protection.

The two step-down converters are highly integrated,

operating at a switching frequency of 1.4MHz, mini-

mizing the size of external components while keep-

ing switching losses low. Each converter has inde-

pendent input, enable, and feedback pins. The out-

put voltage ranges from 0.6V to V

IN

. Each converter

is capable of delivering up to 600mA of load current.

The AAT2550 is available in a Pb-free, space-sav-

ing, thermally-enhanced QFN44-24 package and is

rated over the -40擄C to +85擄C temperature range.
