LoginThe AAT2552 is a fully integrated 500mA battery charger, a 300mA step-down converter, and a 300mA low dropout (LDO) linear regulator. The input voltage range is 4V to 7.5V 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 lithium-ion/polymer batteries.
