IR Advances M3G Series of Space Level DC-DC Converters with DSCC SMDs
International Rectifier Corp., (IR)® announced that the Defense Supply Center Columbus (DSCC) has issued additional Standard Microcircuit Drawings (SMDs) for its family of high-reliability dc-dc converters to include the majority of IR's M3G series of space level dc-dc converters. With the addition of these 40 new DSCC SMDs, the total number of International Rectifier dc-dc SMDs complying with the MIL-PRF-38534 performance specification now stands at more than 500. For systems designers involved in Department of Defense programs, this action simplifies procurement and support tasks for high-reliability microcircuits they select.
"Having our M3G series now DSCC qualified simplifies the design cycle and furthers our continuing efforts for off-the-shelf radiation-hardened dc-dc converters. The M3G series reduces power architecture development and sourcing costs while providing critical electrical and environmental performance," said Robert Gendron, International Rectifier's Executive Director of Marketing.
The M3G converters are complete single-ended forward buck converter "building blocks" for 28, 50 and 70V-input power buses. These converters are offered in single-, dual- or triple-output configurations and are targeted for space level applications. Each module is assembled, tested and documented to reduce or eliminate time needed for analysis and documentation of "in-house" circuit designs. The new converters simplify integration since EMI filtering as well as frequency and phase synchronization are built-in.
Michael G. Daly, International Rectifier's Director of Quality Assurance said, "International Rectifier has a well-established heritage in aerospace and defense applications. This recent release of 40 SMDs demonstrates our continued commitment to the Defense Logistics Agency's SMD Program, DSCC, and our customers."
An SMD is a document that makes an effort to delineate the US Government's requirements for a certain existing commercial microcircuit which is tested for a military application. SMDs specify configuration, physical envelope size, mounting and mating dimensions, interface characteristics, performance requirements, and inspection and test requirements as may be applicable to a specific military environment. The SMD program was created to streamline hardware procurement by reducing the proliferation of contractor-based drawings and specifications.
