PE2118

PE2118 Synchronous Boost DC/DC Regulator PE2118 Features Up to 96% Efficiency Low voltage start-up 0.9V Shut-down current: < 1 A Input voltage Output voltage with Schottky) 0.6V 2.5V 4.4V 4.3V (Up to 5V Description The PE2118 is high efficiency synchronous, PWM step-up DC/DC converters optimized to provide a high efficient solution to medium power systems. The devices work under the input voltage between 0.6V and 4.4V with a 1.4MHz fixed frequency switching. These features minimize overall solution footprint by allowing the use of tiny, low profile inductors and ceramic capacitors. The PE2118 is capable of supplying an output voltage between 2.5V and 4.3V, the internal synchronous switch is desired to provide high efficiency without Schottky. The devices also featured providing up to 260mA from a single AA cell input or up to 600mA from a 2-cell AA with a 3V/3.3V output. The PE2118 regulators are available in the industry standard SOT-23-6 power packages (or upon request). Low switch on resistance RDS(ON), Internal switch: 0.35 1.4MHz fixed frequency switching High switch on current: 1A Short-Circuit protection Low profile SOT-23-6 package (lead-free packaging is now available) Applications Digital cameras and MP3 Palmtop computers / PDAs Cellular phones Wireless handsets and DSL modems PC cards Portable media players Order Information PE2118 SYMBOL A : Adjustable Output Denotes Package Types: F: SOT-23-6 : DESCRIPTION Denotes Output voltage: - 1 - Free Datasheet http:...
