Quarter-Brick Supplies Are Rated To 300 W

Available with nominal output voltages from 2.5 to 12 V and power ratings to 300 W, the iQL and iQG series power supplies are fully regulated and deliver excellent performance in the industry-standard quarter-brick footprint. The single-board, open-frame converters offer up to 95% efficiency, 181 W.in.³ power density, and up to 60 A of useable output current. Most models use metal base plates that facilitate conduction cooling when needed. The iQL series is well-suited for powering distributed, intermediate and Advanced Telecom Computing Architecture bus applications. For conventional power rails, the “standard” outputs of 2.5, 3.3, and 5 V are equipped with both remote sense and output trim (?20/+10%), suitable for powering a wide array of devices. The 8.3- and 12-V output models feature output trim (+20/?10%) without remote sense. Input voltage ranges are either 18 to 36 V or 36 to 75 V. Output power ratings range from 150 W to 300 W depending upon the output voltage. The iQG Series has a nominal output of 12 V at 25 A, providing up to 300 W of continuous output power. They can operate from a wide range input of 36 to 75 V dc and are suitable for distributed and intermediate bus applications that have limited airflow available for cooling. The iQL and iQG series are available now starting at $58 each in 500-piece quantities. TDK-LAMBDA, San Diego, CA. (619) 575-4400.
