DATA SHEET

AAT2785

Three-Channel Step-Down DC/DC Converter

General Description

Features

The AAT2785 is a 3-channel 1.8MHz step-down con-

verter for applications where power efficiency and solu-

tion size are critical. The input voltage range is 2.7V to

5.5V and the outputs are adjustable from 0.6V to V_IN.

• V_INRange: 2.7 to 5.5V

• Output Voltage Range: 0.6V to V_IN

• Output Current:

Channel 3: 1.5A

Channel 1: 600mA

Channel 2: 600mA

▪

The AAT2785 incorporates a unique low noise architec-

ture 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 com-

ponents. The AAT2785 requires a minimum of external

components to realize a high efficiency triple-output buck

converter minimizing solution cost and PCB footprint.

▪

• Low Noise Light Load Mode

• Low Ripple PWM Mode

• Highly Efficient Step-Down Converters

• Low R_DS(ON)Integrated Power Switches

• 100% Duty Cycle

• 1.8MHz Switching Frequency

• Internal Soft Start

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.

• Fast 150μs Turn-On Time

• Over-Temperature Protection

• Current Limit Protection

• TDFN34-16 Package

• -40°C to 85°C Temperature Range

The AAT2785 is available in a Pb-free 16 pin TDFN34

package, and is rated over the -40°C to +85°C operating

temperature range.

Applications

• Cellular and Smart Phones

• Digital Cameras

• Handheld Instruments

• Mass Storage Systems

• Microprocessor / DSP Core / IO Power

• PDAs and Handheld Computers

• Portable Media Players

• USB Devices

• Wireless LAN
