austriamicrosystems Unveils 5V 130mA Step-up DC-DC Converter; AS1321 High Efficiency Step-up DC-DC Converter Supplies Fixed Output of 5V for Battery Powered Applications Where Small Size and Low Power Consumption Are Critical.UNTERPREMSTAETTEN, Austria -- austriamicrosystems (SWX SWX Swiss Exchange (trademark of SWX Swiss Exchange) SWX SolidWorks (3D solid modeling CAD software) SWX Splitter / Wave Division Multiplexer :AMS AMS - Andrew Message System ), a leading global designer and manufacturer of high-performance analog integrated circuits Integrated circuits Miniature electronic circuits produced within and upon a single semiconductor crystal, usually silicon. Integrated circuits range in complexity from simple logic circuits and amplifiers, about 1/20 in. (1. (ICs), today announced the AS1321, a high efficiency step-up DC-DC DC-DC Direct Current to Direct Current (power conversion) converter with a fully integrated synchronous rectifier rectifier, component of an electric circuit used to change alternating current to direct current. Rectifiers are made in various forms, all operating on the principle that current passes through them freely in one direction but only slightly or not at all in the . The AS1321 improves on the excellent performance of the existing AS1320 while boosting the output voltage to 5V. With a supply voltage of 1.5 to 5.0V the AS1321 is capable of delivering a 130mA output current at 2V input voltage. With an efficiency of 96% the AS1321 is the ideal solution for battery powered portable applications that require a 5.0V supply voltage. "The high output current combined with the low power consumption makes the AS1321 an ideal solution for battery powered devices like medical and diagnostics devices, digital cameras, PDA's and smart phones, cordless phones A wireless telephone that transmits to and receives signals from a base station within a range of a few hundred feet. Cordless phones are for local use and cannot travel long distances as can cellphones and satellite phones. See DECT and multihandset cordless. and other handheld products," said Walter Moshammer, marketing director for standard linear at austriamicrosystems. "The AS1321 is also particularly well suited for dual-cell powered battery devices." The AS1321 features a shutdown mode where it draws less than 1uA. In this mode the battery is connected directly to the output to enable direct battery feed-through. This enables the input battery to be used as backup or as a real-time clock A real-time clock (RTC) is a computer clock (most often in the form of an integrated circuit) that keeps track of the current time. Although the term often refers to the devices in personal computers, servers and embedded systems, RTCs are present in almost any electronic supply when the converter is off and eliminates the need for an expensive back-up battery. To ensure stable operation the integrated power on reset circuitry enables the AS1321 to reset any type of microprocessor after power up ensuring a stable start in all devices. The AS1321 is available in a SOT23-6pin package. Refer to the AS1320 for a 3.3V variant.
