Sunnyvale, Calif.—Advanced Analogic Technologies says its AAT1110 is the industry’s first 800-mA step-down regulator that can squeeze into a SC70JW package.
"Designers of cellular phones, digital cameras, and other small portable devices continue to expand their feature set and, in the process, move to higher performance processors that demand increased levels of power," said Bill Weiss, Product Line Director. "By mounting an 800-mA converter in a SC70JW (2-by-2.1 mm) package, the AAT1110 can deliver the higher current these new designs require and still enable the smallest solution size possible." As for performance, the company touts the chip's extremely fast response—sufficient to meet the transient load requirements for powering the baseband chipset in GSM phones.
The AAT1110, working from a 2.7- to 5.5-volt input, is available in fixed-output and adjustable versions down to 0.6 volt (external feedback resistors required).
Features include integrated soft-start capability to eliminate output voltage overshoot on enable or power-up conditions, cycle-by-cycle peak current limiting, over-temperature protection circuitry, and 1.4 MHz operation, which minimizes the size of external inductors and capacitors.
