Bel Fuse SQ24S10050-NS00G

The SemiQ™ Family of DC-DC converters provides a high efficiency single output in a size that is only 60% of industry-standard quarter-bricks, while preserving the same pinout and functionality. In high temperature environments, for output voltages ranging from 3.3 V to 1.0 V, the thermal performance of SemiQ™ converters exceeds that of most competitors' 20 - 30 A quarter-bricks. This is accomplished through the use of patent pending circuit, packaging and processing techniques to achieve ultra-high efficiency, excellent thermal management and a very 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 electric and thermal design, results in a product with extremely high reliability. Operating from an 18 - 36 V input, the SQ24 Series converters of the SemiQ™ Family provide any standard output voltage from 12 V down to 1.0 V. Outputs can be trimmed from -20% to +10% of the nominal output voltage (±10% for output voltages 1.2 V and 1.0 V), thus providing outstanding design flexibility. With a standard pinout and trim equations, the SQ24 Series converters are perfect drop-in replacements for existing quarter brick designs. Inclusion of this converter in new designs can result in significant board space and cost savings. The device is also available in a surface mount package. In both cases the designer can expect reliability improvement over other available converters because of the SQ24 Series’ optimized thermal efficiency.
