SemiQ

SQM48 Series Data Sheet

Family 25A DC-DC Converters

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.

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.
