M3L2805D Datasheet | Micross

Description The M3L-Series of DC-DC converters are radiation tolerant, high reliability devices designed for moderate radiation environments such as those encountered by low earth orbit satellites and launch vehicles. For higher radiation environments, the M3G-Series of DC-DC converters is remended. Features include small size, low weight and a high tolerance to total ionizing dose, single event effects and environmental stresses such as temperature extremes, mechanical shock, and vibration. All ponents are fully de-rated to meet the requirements of MIL-STD-975 and MIL -STD-1547 and GSFC PPL-21 Appendix B. Extensive documentation including Radiation Susceptibility, Thermal Analysis, Stress Analysis and MTBF are available. The converters incorporate a fixed frequency single forward topology with magnetic feedback and an internal EMI filter. These converters are capable of meeting the conducted emissions and conducted susceptibility requirements of MIL -STD-461C without any additional ponents. All models include an external inhibit port and have an adjustable output voltage. They are enclosed in a hermetic 1.5" x 2.3" x 0.425" steel package and weigh less than 85 grams. The package utilizes rugged ceramic feed-through copper core pins and is sealed using parallel seam welding. Manufactured in a facility fully qualified to MIL-PRF-38534, these converters are fabricated utilizing DLA Land and Maritime qualified processes. For available screening options, refer to device screening table in the data sheet. Non-flight versions of the M3L-Series converters are available for system development purposes. Variations in electrical specifications and screening to meet custom requirements can be acmodated. Consult IR Hi Rel San Jose for special requirements. M3L Features - Total Dose > 25 k Rads(Si) - SEE Hardened to LET up to 37 Me V.cm2/mg - Internal EMI filter; Converter Capable of meeting MIL-STD-461C CE03 and CS01 - Low Weight < 85 grams - Magnetically Coupled Feedback - 16V...
