Description
The 20A 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 20A SQM48 Series converters of the SemiQ Family provide thermal performance in high temperature
environments that exceeds most competitors' 20-25 A quarter-bricks. This is accomplished through the use of
patent pending circuit, 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 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.
Operating from a 36-75 V input, the 20A SQM48 Series converters provide any standard output voltage from
3.3 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.
With a standard pinout and trim equations, the SQM48 Series converters are perfect drop-in replacements for
existing 20 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 improvement over other available converters because of the
SQM48 Series’ optimized thermal efficiency.
