TDK-Lambda Expands Quarter Brick Line
San Diego, CA – June 2009 – TDK-Lambda has expanded its impressive line of high power quarter brick modules with the introduction of the iQL and iQG Series. Available with nominal output voltages from 2.5V to 12V and power ratings up to 300-watts, these wide input range fully-regulated and isolated DC-DC converters deliver exceptional performance in the industry standard DOSA quarter brick footprint.
The iQL/iQG Series has been designed with confined space and demanding thermal environments in mind as required in Telecom, Datacom, Wireless and many other applications including Test & Measurement, Broadcast, Robotics and Industrial Controls. These single board open-frame converters offer up to 95% efficiency, 181W per cubic inch power density and up to 60A of useable output current. Metal baseplates are provided on most models to facilitate conduction cooling when needed.
By integrating TDK's latest custom ASIC control devices, newest ferrite cores and multi-layer capacitors, engineers at TDK-Lambda have reduced the component count significantly, providing in a single-board solution with a low height of only 0.52-inch (13.2 mm) the same output power formerly only available on two-board designs. Further, the optimized reduced component count layout and high power density of the iQL/iQG Series provides a more reliable and very cost effective solution.
The fully regulated iQL Series are ideal for powering distributed, intermediate and Advanced Telecom Computing Architecture (ATCA) bus applications. For conventional power rails, the 'standard' output voltages of 2.5V, 3.3V and 5V are equipped with both remote sense and output trim (-20/+10%), suitable for powering a wide array of devices. The 8.3V and 12V output models feature output trim (+20/-10%) without remote sense. This family also boasts wide input voltage ranges of either 18-36V or 36-75V. Output power ratings range from 150W to 300W depending upon the output voltage.
The iQG Series is available with a nominal 12V at 25A output, providing up to 300-watts of continuous output power. They can operate from a wide range input of 36-75VDC and are ideal for distributed and intermediate bus applications that have limited airflow available for cooling.
The iQL/iQG is fully isolated from the input to output and input to baseplate (1500VDC). Standard features include fixed frequency operation, remote on/off, monotonic and pre-bias load start up, auto-recovery from input under-voltage, plus over-current, over-voltage and over-temperature protection circuitry.
These converters are approved to a wide range of national and international safety standards, including UL60950 (US & Canada), VDE 0805 and CB scheme (IEC950) and are RoHS compliant. In addition they carry the CE Mark (EN60950) and come with TDK-Lambda's 3-year warranty.
The iQL and iQG series are available now and priced from $58.00each in 500-unit quantities. More information can be found at TDK-Lambda's web site www.us.tdk-lambda.com/lp
