AAT2512

Dual 400mA High Frequency Buck Converter

™

SystemPower

General Description

Features

The AAT2512 is a member of AnalogicTech's Total

Power Management IC™ (TPMIC™) product fam-

ily. It is a dual channel synchronous buck convert-

er operating with an input voltage range of 2.7V to

5.5V, making it ideal for applications with single-

cell lithium-ion/polymer batteries.

•

V_INRange: 2.7V to 5.5V

Output Current:

— Channel 1: 400mA

— Channel 2: 400mA

Available in TDFN33-12 Package

-40°C to +85°C Temperature Range

Both regulators have independent input and

enable pins. Offered with fixed or adjustable out-

put voltages, each channel is designed to operate

with 27µA (typical) of quiescent current, allowing

for high efficiency under light load conditions.

The AAT2512 requires only three external compo-

nents (C_IN, C_OUT, and L_X) for each converter, mini-

mizing cost and real estate. Both channels are

designed to deliver 400mA of load current and

operate with a switching frequency of 1.4MHz,

reducing the size of external components.

Applications

The AAT2512 is available in a Pb-free, 12-pin

TDFN33 package and is rated over the -40°C to

+85°C temperature range.
