The MilQor
®
series of high-reliability DC-DC converters
brings SynQor’s field proven high-efficiency synchronous
rectifier technology to the Military/Aerospace industry.
SynQor’s innovative QorSeal
TM
packaging approach ensures
survivability in the most hostile environments. Compatible
with the industry standard format, these converters operate
at a fixed frequency, have no opto-isolators, and follow
conservative component derating guidelines. They are
designed and manufactured to comply with a wide range of
military standards.
Design Process
MQFL series converters are:
• Designed for reliability per NAVSO-P3641-A guidelines
• Designed with components derated per:
— MIL-HDBK-1547A
— NAVSO P-3641A
