SynQor Introduces 28Vin DC-DC Converters to the Mil-COTS Market

Mil-COTS converters in half-brick, quarter-brick, and sixteenth-brick packages Full power operation from -55°C to +100°C

Boxborough, MA - December 14, 2009 - SynQor announces the release of its Mil-COTS 28 series of isolated DC-DC converters, expanding its MilQor offerings for the Military and Aerospace industries. These “off-the-shelf” converters operate from an input voltage of 16V to 40V continuously and will withstand 50V transients for up to 1 second, meeting MIL-STD-704D input voltage range requirements. Designed for cost sensitive Mil-COTS applications, these ruggedized, encased packages ensure survivability in demanding environments. SynQor brings its field proven, synchronous rectification technology to provide high efficiency converters that are designed and manufactured to comply with a wide range of military standards.

The high power density half-brick, quarter-brick and sixteenth-brick packages are fully encased and have industry standard footprints and pinout configurations. Although these efficient designs do not require a heatsink, the encased package will accommodate standard DC-DC converter heatsinks. A flanged baseplate version is also available.

The Mil-COTS 28 series undergo stringent qualification and characterization, with full component traceability and unique part serialization and are designed to conservative component derating guidelines. These converters are available in two options, an S-Grade or a more extensive M-Grade screening.

Fourteen output voltages from 1.2V to 50V have an adjustable trim from +10% to -20% (+/-10% for sixteenth-brick) to meet numerous application requirements. The fixed switching frequency design yields predictable EMI filtering and, when used in conjunction with a Mil-COTS EMI filter, differential mode noise is attenuated by more than 80dB and common-mode noise is attenuated by more than 36dB.

Protection features include input under-voltage lockout, output current limit and short circuit protection, active back-bias limit, output over-voltage protection and thermal shutdown. All models have at least 2250Vdc isolation rating between input and output, are rated with MTBF values in excess of 1MHrs at a baseplate temperature of 70°C.

The Mil-COTS 28 series of products are available immediately from stock for evaluation and qualification. Production quantities are available with 12 week lead-times, depending upon volumes. For more information please visit or contact your local SynQor representative.
