International Rectifier Corp. (IR, El Segundo, CA) introduced the M3L28 family of standard, off-the-shelf, radiation-tolerant, dc/dc converter "building blocks" that address space industry demand for shorter design cycles and less costly design analyses. The M3L dc/dc converters feature high reliability, and are designed for extended operation in moderate radiation environments such low Earth orbit satellites and launch vehicles.
The converters are designed to operate without performance or power derating under the temperature extremes of –55°C to +125°C. The new converters are targeted for point-of-load regulation for power systems, and feature hybrid assembly technology, to minimize size and weight. The products are available in the most common input voltage of 28V, with standard output voltages of 3.3V, 5V, 12V and 15V for single-output models, and ±5V, ±12V and ±15V for dual-output models. The converters include an input EMI filter that is capable of meeting the conducted emissions and conducted susceptibility requirements of MIL-STD-461C.
Samples and flight units are available now. The M3L28xxS is $2,650 each and the M3L28xxD is $2,675 each in 50-lot quantities.
