Description

The SemiQ™ Series of dc-dc converters provides a high-efficiency single output in a size that is only 60% of

industry-standard quarter-bricks, while preserving the same pinout and functionality.

In high temperature environments, for output voltages ranging from 3.3 V to 1.0 V, the thermal performance of

SemiQ™ converters exceeds that of most competitors' 20-25 A quarter-bricks. This performance 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 SQ48 Series converters provide any standard output voltage from 12 V down

to 1.0 V. Outputs can be trimmed from –20% to +10% of the nominal output voltage (±10% for output voltages

1.2 V and 1.0 V), thus providing outstanding design flexibility.

With a standard pinout and trim equations, the SQ48 Series converters are perfect drop-in replacements for

existing quarter-brick designs. Inclusion of this converter in new designs can result in significant board space and

cost savings. In both cases the designer can expect reliability improvement over other available converters

because of the SQ48 Series’ optimized thermal efficiency.
