Designers of portable devices continue to expand their feature set and in the process move to higher performance processors that demand increased levels of power. By mounting an 800 mA DC-DC converter in a tiny SC70JW package, AnalogicTech's new AAT1110 part delivers the higher current that these new designs require yet still enables small solution size.
Optimised for extremely fast transient response, this latest voltage converter is well suited for powering up heavy loads in high performance, ultra-portable convergent systems, such as PDA handsets and smartphones. The AAT1110 operates across an input range of 2,7 V to 5,5 V, and output levels as low as 0,6 V. The device delivers up to 800 mA of current while maintaining a low 27 μA no load quiescent current. It is available in either a fixed version with internal feedback or a programmable version with external feedback resistors.
A high 1,4 MHz switching frequency helps reduce solution footprint by allowing the use of extremely small external inductors and capacitors. Integrated soft-start capability eliminates any output voltage overshoot when the enable or input voltage is applied. To protect itself from overload conditions, the AAT1110 limits peak current after a current limit has been sensed over a series of clock cycles. An over-temperature protection circuit additionally disables switching once internal dissipation reaches a pre-set level.
The AAT1110 is specified over the -40 to +85°C and comes in a Pb-free, 8-pin, 2,0 x 2,1 mm SC70JW package.
