General Description

The AAT2789 is a 2-channel synchronous step-down converter operating from an input voltage range of 2.7V to 5.5V, making it the ideal choice for single-cell Lithiumion/polymer battery powered systems or low voltage 3.3V and 5V based consumer equipment.

Channel 1 delivers up to 1700mA output current while Channel 2 delivers up to 800mA.

Both converters incorporate a unique low noise architecture which reduces output ripple and spectral noise.
