AnalogicTech Announces 3A Step-Down Converter for 12V Industrial Applications

Power Efficient Device Helps Backplane-based Equipment Designers Meet Rigorous
Environmental Standards

SANTA CLARA, Calif., Jan. 22 /PRNewswire-FirstCall/ -- Advanced Analogic
Technologies Inc. (AnalogicTech(TM)) (Nasdaq: AATI), a developer of power
management semiconductors for mobile consumer electronic devices, announced
today the AAT1160, a synchronous step-down DC/DC converter delivering up to 3A
output from a 12V input. Combining high power efficiency levels and a very low
150 uA quiescent current, the AAT1160 offers power savings in a variety of
industrial applications, especially those using backplanes, as well as
portable systems running off two-cell Lithium-ion batteries.

"Maximizing power efficiency and minimizing power consumption to meet
emerging green energy standards is becoming increasingly important in more and
more industrial applications where it traditionally wasn't even considered
before," said Bill Weiss, product line director for AnalogicTech. "By
capitalizing on our proprietary ModularBCD(TM) process technology, minimizing
quiescent current consumption and using a synchronous design, the AAT1160
delivers significant power savings to tightly packed rack-mounted,
backplane-based systems such as telecommunications switches, cellular base
stations and server farms."
High efficiency, low quiescent current
The AAT1160 current-mode, step-down DC/DC converter operates across a wide
4V to 13.2V input voltage range. It supplies a load current up to 3A with a
fixed or adjustable output voltage which can be regulated to as low as 0.6V.
The device supports efficiency levels up to 96%. Leveraging AnalogicTech's
extensive expertise in portable applications, the AAT1160 also consumes an
industry-leading low 150 uA no-load quiescent current. The AAT1160 maintains
high efficiency over the entire load range. The user can select to operate the
device in a forced Pulse Width Modulation (PWM) mode and synchronize the
switching to an external signal to control switching noise. The high 800 kHz
switching frequency also minimizes total solution size by allowing the use of
small external components.
A soft start function limits input surge current and eliminates output
voltage overshoot when the device is turned on. The AAT1160 also features
short-circuit and over-temperature protection.
ModularBCD process
The AAT1160's excellent performance and low power consumption is also a
product of AnalogicTech's Modular BCD process technology. Compared to
linear-IC legacy fabs and generic digital CMOS foundries, ModularBCD provides
more cost-effective, modular fabrication of analog, power and mixed-signal ICs
by monolithically integrating fully-isolated CMOS at multiple voltages,
complementary bipolar transistors, and robust power devices. This process
avoids complex and expensive techniques such as epitaxy and high-temperature
diffusion. Devices manufactured in ModularBCD offer higher efficiency, smaller
size and higher levels of integration than those fabricated in many other
processes. They also offer designers better ability to manage power and extend
battery life in a wide range of mobile consumer electronics products such as
cell phones, portable media players, tablet and laptop computers and digital
cameras.
Price and Availability
Qualified across the -40 C to +85 C temperature range, the AAT1160 is
available in a Pb-free, 16-pin 3 mm X 4 mm TDFN package. It sells for $1.82 in
1K quantities.
