AAT2554 Overview
The AAT2554 is a fully integrated 500mA battery charger, a 250mA step-down converter, and a 300mA low dropout (LDO) linear regulator. The input voltage range is 4V to 6.5V for the battery charger and 2.7V to 5.5V for the step-down converter and linear regulator, making it ideal for applications operating with single-cell lithiumion/polymer batteries. The battery charger is a plete constant current/constant voltage...
