PRODUCT DATASHEET

AAT1160

SwitchReg^TM

12V, 3A Step-Down DC/DC Converter

General Description

Features

The AAT1160 is an 800kHz high efficiency step-down

DC/DC converter. With a wide input voltage range of

4.0V to 13.2V, the AAT1160 is an ideal choice for dual-

cell Lithium-ion battery-powered devices and mid-pow-

er-range regulated 12V-powered industrial applications.

The internal power switches are capable of delivering up

to 3A to the load.

• Input Voltage Range: 4.0V to 13.2V

• Up to 3A Load Current

• Fixed or Adjustable Output:

Output Voltage: 0.6V to V_IN

▪

• Low 150μA No-Load Operating Current

• Less than 1μA Shutdown Current

• Up to 96% Efficiency

• Integrated Power Switches

• 800kHz Switching Frequency

The AAT1160 is a highly integrated device, simplifying

system-level design. Minimum external components are

required for the converter.

Synchronizable to External Clock

Forced PWM or Light Load Mode

• Soft Start Function

▪

The AAT1160 optimizes efficiency throughout the entire

load range. It operates in a combination PWM/Light Load

mode for improved light-load efficiency. It can also

operate in a forced Pulse Width Modulation (PWM) mode

for easy control of the switching noise as well as faster

transient response. The high switching frequency allows

the use of small external components. The low current

shutdown feature disconnects the load from V_INand

drops shutdown current to less than 1μA.

• Short-Circuit and Over-Temperature Protection

• Minimum External Components

• TDFN34-16 Package

• Temperature Range: -40°C to +85°C

Applications

• Distributed Power Systems

• Industrial Applications

• Laptop Computers

• Portable DVD Players

• Portable Media Players

• Set-Top Boxes

The AAT1160 is available in a Pb-free, space-saving,

thermally-enhanced 16-pin TDFN34 package and is rated

over an operating temperature range of -40°C to

+85°C.

• TFT LCD Monitors and HDTVs
