SynQor Develops the First Extended Input Range DC-DC Converters & Filters Specifically for Military Applications

MilQor® Hi-Rel Series; Packaged for harsh environments; Wide range of single and dual output voltages

Boxborough, MA - June 4, 2009 - SynQor announces the addition of a new product family to its portfolio of Hi-Rel DC-DC converters, the MQFL-28E series. Incorporating SynQor’s field proven high-efficiency synchronous rectifier technology, this advancement results in the only wide range input DC-DC converters developed specifically for the Military/Aerospace industry.

The MQFL-28E family handles up to 120W while meeting the long-term over-voltage surges in the input voltage specified by MIL STD 704(A-F), RTCA/DO-160E, and DEF STAN 61-5. The MQFL-28E converters accept continuous input voltages of 16-70 V while permitting broader transient input voltages of 16-80V for 1 second.

The MQFL-28E series is available in eleven standard single output voltages including 1.5V, 1.8V, 2.5V, 3.3V, 5V, 6V, 7.5V, 9V, 12V, 15V and 28V. Dual output converters are also available with output voltages of +/-5V, +/-12V and +/-15V with the capability of providing up to 80% power from either output. These feature-rich MilQor Hi-Rel MQFL-28E converters operate at efficiencies up to 91% and are designed to operate from -55°C to +125°C with multiple screening options for stringent environmental requirements.

The MQFL-28E family of DC-DC converters is housed in the full-size (FL) industry standard package using SynQor’s innovative QorSeal™ packaging technology which ensures survivability in harsh environments, long-term storage and provides the latest technology in tin whisker mitigation. Standard features include fixed switching frequency, parallel operation with current share, remote sensing, output trim adjust, clock synchronization, primary and secondary referenced enable, continuous short circuit and overload protection, and input under-voltage lockout and input over-voltage shutdown. Complimentary MQME-28E EMI filter module solutions rated at 320W (20A) are available which include transient suppression circuitry, enable pass-through circuitry, and reverse polarity protection.

The MQFL-28E converters are compatible with industry standard formats, have no opto-isolators, and follow NAVSO P3641A & MIL-HDBK-1547A component derating guidelines. MQFL-28E MilQor converters are designed and manufactured to comply with a wide range of military standards, including Mil-Std-461(C, D, E) and RTCA/DO-160E (Section 22).

Compared with hybrid chip-and-wire converters, the MQFL-28E portfolio of Hi-Rel DC-DC converters is a competitively priced solution. Sample quantities are readily available, and production quantities are available with a standard lead-time of 12-16 weeks ARO, depending on screening options.
