di/dt Inc. (Carlsbad, CA), a Power-One Inc. (Camarillo, CA) company, announced the 24V input SemiQ™ eighth-brick family of dc/dc converters, the SQ24, which comes in a package size that is only 60% the area of the industry-standard quarter-brick and delivers up to 15A of output current with minimal or no derating at elevated temperatures and low airflow.
The power density of 90W/in³ (5.7W/cm³) sets a new standard for 24V input converters in a 2in² (13.3cm²) converter package. The SQ24 converters are pin-for-pin compatible with larger quarter-bricks. The SQ24 converters come in an open-frame package that does not require a heatsink. They have dimensions of 0.9in x 2.3in x 0.26in (22.8mm x 58.4mm x 6.6mm), and weigh only 15g (0.53oz).
The SQ Series operates from an input voltage of 18Vdc to 36Vdc and are available in standard output voltages of 12V, 8V, 6V, 5V, 3.3V, 2.5V, 2V, 1.8V, 1.5V, 1.2V and 1V. The converters come in both through-hole and surface-mount packages. The surface-mount version is shipped in tape-and-reel packing to facilitate automatic handling and pick-and-place assembly. In quantities of 1,000 pieces, the SQ24 family is priced at $55. Samples and production are available now.
