austriamicrosystems Expands Portfolio of High Efficiency Step-up DC-DC Converter for Battery Powered Products.UNTERPREMSTAETTEN, Austria -- AS1325 step-up DC-DC DC-DC Direct Current to Direct Current (power conversion) Converter Supplies 300mA Output Current for Portable Products Where Smallest Size and Lowest Power Consumption Are Critical 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 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) for communication, industrial, medical and automotive applications, today announced the expansion of its family of step-up DC-DC converters with the introduction of the AS1325, a high efficiency step-up DC-DC 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 . With an efficiency of 96 percent, the AS1325 is an ideal solution for battery powered portable applications with the need for 3.3V or 5.0V supply voltage. Improving on the performance of the company's AS1320 and AS1321 DC-DC converters, the AS1325 offers significantly increased output current, providing a supply voltage of 1.5 to 3.5V (for 3.3V output voltage) or 1.5 to 5.0V (for 5.0V output voltage). Supplied with less than 2V, the AS1325 is capable of delivering a 300mA output current at 5.0V output voltage or 185mA at 3.3V output voltage. The AS1325 features a shutdown mode where it draws less than 1(mu)A. 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 AS1325 to reset any type of microprocessor after power up to provide a stable start. "The high output current combined with low power consumption and high efficiency makes the AS1325 an ideal solution for battery powered devices like medical and diagnostics equipment, digital cameras, MP3 players A digital music player that supports the MP3 format, which was the audio format that started a revolution in online music downloads and distribution. All portable music players, the iPod being the most popular, support MP3 along with one or more other audio formats. , PDAs and smart phones, cordless phones and other handheld products," said Walter Moshammer, standard linear marketing director at austriamicrosystems. "The outstanding efficiency of 96 percent helps to significantly extend the battery life of dual-cell battery powered devices." The AS1325 is available in a 6-pin SOT23 package.
