Description
The new high temperature SQE48-Series of dc-dc converter provides a high efficiency single output in a physical
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 SQE48-Series of converters utilizes the
same pinout and functionality of the industry-standard quarter-bricks.
The SQE48-Series of converters provides thermal performance in high temperature environments that exceeds
most competitors' 20 A 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 airflow shadowing, thus enhancing cooling for
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.
The SQE48T20050 operates over an input voltage range of 36 to 75 VDC, and provides an output current up to
20 A with a standard output voltage of 5.0 VDC. The output can be trimmed from –20% to +10% of the nominal
output voltage, thus providing outstanding design flexibility.
With standard pinout and trim equations, the SQE48 converters are perfect drop-in replacements for the
competing quarter-brick designs. Inclusion of this converter in new designs 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.
