Description
The new high performance 20A SQL48T20033 DC-DC converter provides a high efficiency single output, in a 1/8
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 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 (-xxxBx suffix) 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 36-75V input, the SQL48T20033 converter provides a fully regulated 3.3V 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 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 SQL48T20033
s optimized thermal efficiency.

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