一,产品概述(General Description) The JTM3400 is high efficiency synchronous, step-up DC/DC converters optimized to provide a high efficient solution to medium power systems. The devices work under the input voltage between 0.9V and 4.4V with a 1.4MHz fixed frequency switching. These features minimizes overall solution footprint by allowing the use of tiny,low profile inductors and ceramic capacitors. The JTM3400 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 JTM3400 regulators are available in the industry standardSOT-23-6 powerpackages (or upon request). 二.产品特点(Features) Up to 96% Efficiency Low voltage start-up:0.9V Shut-down current: < 1µA Input voltage:0.9V~4.4V Output voltage:2.5V~4.3V (Up to 5V with Schottky) Low switch on resistance RDS(ON), Internal switch: 0.35Ω 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) 三,应用范围 (Applications) Digital cameras and MP3 Palmtop computers / PDAs Cellular phones Wireless handsets and DSL modems PC cards Portable media players 四,产品封装图 (Package) (1)JTM3400 ![]()
