AAT2784中文资料3-Channel Step-Down DC/DC Converter数据手册Skyworks规格书

描述 Description

The AAT2784 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.
Channel 3 delivers up to 1.5A output current and channels 1 and 2 deliver up to 300mA each. The AAT2784 uses a high switching frequency to minimize the size of external components. The AAT2784 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 AAT2784 is available in a Pb-free 16 pin TDFN34 package, and is rated over the -40°C to +85°C operating temperature range.
