AAT1162

12V, 1.5A Step-Down DC/DC Converter

Features

General Description

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-pow-

er-range regulated 12V-powered 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 150μA No-Load Operating Current

• Less than 1μA Shutdown Current

• Up to 96% Efficiency

• Integrated Power Switches

• 800kHz Switching Frequency

• Soft Start Function

• Short-Circuit and Over-Temperature Protection

• Minimum External Components

• TDFN34-16 Package

The AAT1162 is a highly integrated device, simplifying

system-level design. Minimum external components are

required for the converter.

The AAT1162 optimizes efficiency throughout the entire

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

mode for improved light-load efficiency. The high switch-

ing frequency allows the use of small external compo-

nents. The low current shutdown 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

• Portable DVD Players

• Portable Media Players

• Set-Top Boxes

The AAT1162 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
