SQM48 Series Data Sheet
SemiQ
The new 25A SemiQ? Family of DC-DC converters provide
a high-efficiency single output in a size that is only 60% of
industry-standard quarter-bricks, while preserving the same
pinout and functionality.
The 25A SQM48 Series converters of the SemiQ? Family
provide thermal performance in high temperature environ-
ments that exceeds most competitors' 25 A quarter-bricks.
This is accomplished through the use of patent pending cir-
cuit, packaging and processing techniques to achieve ultra-
high efficiency, excellent thermal management and a very

low body profile.
Low body profile and the preclusion of heatsinks minimize
airflow shadowing, thus enhancing cooling for downstream
devices. The use of 100% automation for assembly, coupled
with advanced electric and thermal design, results in a prod-
uct with extremely high reliability.
Operating from a 36-75 V input, the 25A SQM48 Series
converters provide any standard output voltage from 2.5 V
down to 1.2 V. Outputs can be trimmed from –20% to +10%
of the nominal output voltage ( ± 10% for output voltage 1.2
V), thus providing outstanding design flexibility.
SQM48T and SQM48S Converters
Features
? RoHS lead-free solder and lead-solder-exempted
products are available
? Delivers up to 25 A (62.5 W)
? Industry-standard quarter-brick pinout
? Extremely small footprint: 0.896” x 2.30” (2.06 in 2 ),
40% smaller than conventional quarter-bricks
? Higher current capability at elevated temperatures
than most competitors' 25 A quarter-bricks
? On-board input differential LC-filter for the lowest input
With a standard pinout and trim equations, the SQM48
Series converters are perfect drop-in replacements for exist-
ing 25 A quarter-brick designs. Inclusion of this converter in
new designs can result in significant board space and cost
savings. The device is also available in a surface mount
package.
In both cases the designer can expect reliability improve-
ment over other available converters because of the SQM48
Series’ optimized thermal efficiency.
