Description
The new high performance 40A SQE48T40018 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 SQE48T40018 converter utilize the
same pinout and functionality of the industry-standard quarter-bricks.
The SQE48T40018 converter provides thermal performance in high temperature environments that exceeds most
40A quarter-bricks in the market. 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 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 36-75V input, the SQE48T40018 converter provides a 1.8V output voltage that can be trimmed
from –20% to +10% of the nominal output voltage, thus providing outstanding design flexibility.
With standard pinout and trim equations, the SQE48T40018 converter is a perfect drop-in replacement for existing
40A 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
SQE48T40018’s optimized thermal efficiency.
