Module DC-DC 1-OUT 3.3V 20A 66W 8-Pin

The new high performance 20 A SQL48T20033 DC-DC converter 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 SQL48T20033 converter utilizes the same pin-out and Input / Output functionality of the industry-standard quarter-bricks. In addition, a heat spreader feature is available that provides an effective thermal interface for coldplate and heat sinking options. The SQL48T20033 converter thermal performance 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 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 wide-range 36-75 V input, the SQL48T20033 converter provides a fully regulated 3.3 V output voltage. The outputs can be trimmed from –20% to +10% of the nominal output voltage, thus providing outstanding design flexibility. Employing a standard power pin-out, the SQL48T20033 converter is an ideal drop-in replacement for existing high current quarterbrick 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 SQL48T20033’s optimized thermal efficiency.
