5-Watt Hi-Rel Isolated/Regulated DC-DC Converters

SynQor, Inc. announces the release of the MQSA-28-05S, the first to come in a new series of low-power, Hi-Rel converters. This 5W dc-dc converter is housed in a new compact package that measures 1.075" x 1.075" x 0.27". Developed specifically for the Military/Aerospace industry to ensure survivability in the most hostile environments, the MQSA-28-05S uses SynQor's innovative QorSeal™ packaging technology, which includes tin whisker mitigation.

The MQSA-28-05S accepts a continuous input voltage of 16-40V, and it is capable of handling a transient input voltage of 50V for 1 second. This over-voltage transient complies with MIL-STD-704F, RTCA/DO-160G Cat A/R, MIL-STD-1275D (Gen+Bat), and DEF-STAN 61-5 (Part 6)/5 (Gen+Bat) limitations.

The MQSA-28-05S converter operates from -55 to 125 degrees C baseplate temperature and provides up to 5W of power at a typical 80% efficiency throughout the temperature profile. It has an input-side referenced enable, an output over-voltage protection, a continuous short circuit and overload protection, as well as input under-voltage shutdown. There are no opto-isolators in the converter.

Designed for reliability per NAVSO-P3641-A guidelines with components derated per MIL-HDBK-1547A and NAVSO-P3641-A, and qualified per MIL-STD-810F- consistent with RTCA/D0-160E, SynQor's First Article Qualification-consistent with MIL-STD-883F, SynQor's Long-Term Storage Survivability Qualification, and SynQor's on-going life tests, these converters are an exceptional choice for low power High Reliability needs. Three separate screening levels are made available for your increasing level of mission critical requirements.
