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.
