Step-Down Converter suits space-constrained applications.

Press Release Summary:

Housed in 2 x 2 mm, 8-pin STDFN package, 500 mA Model AAT1120 operates over 2.7-5.5 V input voltage range. Output voltage is adjustable from 0.6 V to VIN and supports 100% duty cycle low dropout operation. Efficiency of 96% extends battery life, while 1.5 MHz switching frequency permits use of small external components. Designed for systems powered by single-cell Li-Ion/polymer battery, device includes over-temperature and current-limit protection.

AnalogicTech Announces 500 mA Step-Down Converter in 2 x 2 x 0.55 mm Package

SUNNYVALE, Calif., April 17 /-- Advanced Analogic Technologies Incorporated (AnalogicTech) (NASDAQ:AATI), a developer of power management semiconductors for mobile consumer electronic devices, announced today the AAT1120, a 500 mA step-down converter in a standard 2 x 2 mm, 8-pin STDFN package. Occupying just 4 mm(2) of PCB area and only 0.55 mm tall, this new addition to AnalogicTech's extensive voltage regulation product line offers attractive space savings for space-constrained portable applications.

"Higher power density is a key benefit aiding engineers' ongoing efforts to shrink their product footprint and thickness and thus build smaller micro hard disc drives, handsets, headsets, handheld instruments and other portable devices," noted Bill Weiss, product line director. "By delivering 500 mA in a tiny, 2 x 2 x 0.55 mm package, the AAT1120 step-down converter allows designers to build smaller, thinner systems and still provide all the features and current found in larger footprint devices."

High efficiency operation
Designed for systems powered by a single-cell lithium-ion/polymer battery, 5 V or 3.3 V VBUS, the AAT1120 operates over a 2.7 V to 5.5 V input voltage range. Output voltage is adjustable from 0.6 V to VIN and supports 100% duty cycle low dropout operation. A 96% efficiency level extends battery life. The converter also offers a low 30 uA no load quiescent current. A 1.5 MHz switching frequency permits the use of small external components while keeping switching losses low.

To ensure device integrity, the AAT1120 features over-temperature and current-limit protection. Soft-start control limits input surge current and eliminates output voltage overshoot.

Price and availability
The AAT1120 is specified across the -40 degrees C to +85 degrees C temperature range and is available in a Pb-free, 8-pin, 2 x 2 mm STDFN package. It sells for $0.85 each in 1,000 piece quantities.
