General Description

Features

The AAT1162 is an 800kHz high efficiency step-

down DC/DC converter. With a wide input voltage

range of 4.0V to 13.2V, the AAT1162 is an ideal

choice for dual-cell Lithium-ion battery-powered

devices and mid-power-range regulated 12V-pow-

ered industrial applications. The internal power

switches are capable of delivering up to 1.5A to the

load.

•

Input Voltage Range: 4.0V to 13.2V

Up to 1.5A Load Current

Fixed or Adjustable Output:

— Output Voltage: 0.6V to V_IN

Low 115µA No-Load Operating Current

Less than 1µA Shutdown Current

Up to 96% Efficiency

Integrated Power Switches

800kHz Switching Frequency

Soft Start Function

•

The AAT1162 is a highly integrated device, simpli-

fying system-level design. Minimum external com-

ponents are required for the converter.

Short-Circuit and Over-Temperature Protection

Minimum External Components

TDFN34-16 Package

The AAT1162 optimizes efficiency throughout the

entire load range. It operates in a combination

PWM/Light Load mode for improved light-load effi-

ciency. The high switching frequency allows the use

of small external components. The low current shut-

down feature disconnects the load from V_INand

drops shutdown current to less than 1µA.

Temperature Range: -40°C to +85°C

Applications

•

Distributed Power Systems

Industrial Applications

Laptop Computers

The AAT1162 is available in a Pb-free, space-sav-

ing, thermally-enhanced 16-pin TDFN34 package-

and is rated over an operating temperature range

of -40°C to +85°C.
