AAT2513

Dual 600mA Step-Down

Converter with Synchronization

™

SystemPower

General Description

Features

The AAT2513 is a high efficiency dual synchronous

step-down converter for applications where power

efficiency, thermal performance and solution size

are critical. Input voltage ranges from 2.7V to 5.5V,

making it ideal for systems powered by single-cell

lithium-ion/polymer batteries.

•

V_INRange: 2.7V to 5.5V

Output Current:

— Channel 1: 600mA

— Channel 2: 600mA

96% Efficient Step-Down Converter

Low No Load Quiescent Current

— 60µA Total for Both Converters

Integrated Power Switches

100% Duty Cycle

•

Each converter is capable of 600mA output current

and has its own enable pin. Efficiency of the con-

verters is optimized over full load range. Total no

load quiescent current is 60µA, allowing high effi-

ciency even under light load conditions.

•

1.7MHz Switching Frequency

Optional Fixed Frequency or External SYNC

Logic Selectable 180° Phase Shift Between

the Two Converters

The integrated power switches are controlled by

pulse width modulation (PWM) with a 1.7MHz typi-

cal switching frequency at full load, which minimizes

the size of external components. Fixed frequency,

low noise operation can be forced by a logic signal

on the MODE pin. Furthermore, an external clock

can be used to synchronize the switching frequency

of both converters.

Cellular Phones / Smart Phones

Digital Cameras

The AAT2513 is available in a Pb-free, thermally

enhanced 16-pin QFN33 package and is specified

for operation over the -40°C to +85°C temperature

range.
