The high temperature 30A SQE48 Series of DC-DC converters provides a high efficiency single output, in a 1/8th brick package that is only 62% the size of the industry-standard quarter-brick. Specifically designed for operation in systems that have limited airflow and increased ambient temperatures, the SQE48T30 converters utilize the same pinout and functionality of the industry-standard quarter-bricks. The 30 A SQE48 Series converters provide thermal performance in high temperature environments that exceeds most competitors' 30A quarter-bricks. This performance is accomplished through the use of patented/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 impedance to system airflow, thus enhancing cooling for both upstream and 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 36-75 V input, the SQE48T30 converters provide any standard output voltage from 3.3 V down to 1.2 V that can be trimmed from -20% to +10% of the nominal output voltage (ยบ 10% for output voltage 1.2 V), thus providing outstanding design flexibility. With standard pinout and trim equations, the SQE48 Series converters are perfect drop-in replacements for existing 30 A quarter-brick designs. Inclusion of this converter in a new design can result in significant board space and cost savings. The designer can expect reliability improvement over other available converters because of the SQE48 Series' optimized thermal efficiency.
