Description

span id="lblDescription">

The AAT2785 is a 3-channel 1.8MHz step-down converter for applications where power efficiency and solution size are critical. The input voltage range is 2.7V to 5.5V and the outputs are adjustable from 0.6V to VIN.

The AAT2785 incorporates a unique low noise architecture which reduces ripple and spectral noise. Channel 3 delivers up to 1.5A output current and channels 1 and 2 deliver up to 600mA each. The AAT2785 uses a high switching frequency to minimize the size of external components. The AAT2785 requires a minimum of external components to realize a high efficiency triple-output buck converter minimizing solution cost and PCB footprint.

Each of the 3 regulators has an independent enable pin, adjustable output voltage and operates with low no load quiescent current, providing high efficiency over the entire load range.

The AAT2785 is available in a Pb-free 16 pin TDFN34 package, and is rated over the -40C to +85C operating temperature range.
