AAT2749 Datasheet (Skyworks) - 3.0MHz Step-Down Converter and Low-V LDO

AAT2749, 3.0MHz Step-Down Converter and Low-V LDO

The AAT2749 is a two channel power regulator that operates from 2.3V to 5.5V.

The AAT2749 contains a 3.0MHz, 600mA step-down converter and a low input voltage 300mA LDO regulator.

The step-down converter can deliver 600mA of load current.

The 3.0MHz switching frequency minimizes the size of external
