The new High Temperature 20 A SemiQ™ Family of DC-DC converters provides a high efficiency single output in a size that is only 60% of industry-standard quarter-bricks. Specifically designed for operation in systems that have limited airflow and increased ambient temperatures, the SQE48T20033 eighth-brick converters utilize the same pinout and functionality of the industry-standard quarter-bricks. The 20 A SQE48T Series converters of the SemiQ™ Family provide thermal performance in high temperature environments that exceeds many competitors' 25 A and 30 A quarter-bricks. This is accomplished through the use of patent pending circuits, packaging, and processing techniques to achieve ultra-high efficiency, excellent thermal management and a low body profile. Low body profile and the preclusion of heat sinks minimize airflow shadowing, thus enhancing cooling for downstream devices. The use of 100% automation for assembly, coupled with advanced electronic circuits and thermal design, results in a product with extremely high reliability. Operating from a 36-75V input, the 20A SQE48T Series converters provides a standard output voltage 3.3V. The outputs can be trimmed from -20% to +10% of the nominal output voltage, thus providing outstanding design flexibility. With standard pinout and trim equations, the SQE48T Series converters are perfect drop-in replacements for competing quarter-brick designs. Inclusion of this converter in new designs can result in significant board space and cost savings. The designer can expect reliability improvement over other available converters because of the SQE48T Series' optimized thermal efficiency.
