The new high performance 20A SQE48T20120 DC-DC converter provides a high efficiency single output, in a 1/8
Description
th
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 SQE48T20120 converter utilizes the
same pin-out and Input/Output functionality of the industry-standard quarter-bricks. In addition, a heat spreader
feature is available (-xxxBx suffix) that provides an effective thermal interface for coldplate and heat sinking
options.
The SQE48T20120 converter thermal 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 wide-range 36-75V input, the SQE48T20120 converter provides a fully regulated 12V output
voltage. Employing a standard power pin-out, the SQE48T20120 converter is an ideal drop-in replacement for
existing high current eighth-brick and 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 SQE48T20120’s optimized thermal efficiency.

Baseplate/heat spreader option (suffix ‘-xxxBx’) facilitates heatsink mounting to further enhance the unit’s thermal capability.
