El Segundo, Calif. - International Rectifier's AMA Series (5W), AMF Series (12W), and AMR Series (30W) of (fully isolated) DC/DC converters are radiation-tolerant, high-reliability devices designed for extended operation in moderate radiation environments.
The new converters, off-the-shelf units, are designed to solve the space industry's problems of lengthy design cycles and extensive design analysis requirements for custom units. Their small size and low mass make them ideal for point-of-load sources or as a building block in a power system for low earth orbit (LEO) satellites and launch vehicles.
The AMA, AMF and AMR converters feature high tolerance to total ionizing dose (TID, greater than 25 krads), heavy ion single event effects (SEE, greater than 60 MeV-cm2/mg) and environmental stresses such as temperature extremes, mechanical shock and vibration. Radiation test data, which include TID and SEE, are available.
The new DC/DC converters have a 28-volt input, with standard output voltages of 3.3, 5, 12 and 15 volts for single-output models, and ±5, ±12 and ± 15 volts for dual-output models. A separate MIL-STD-461C compliance filter is available.
The AMA series converters weigh less than 32 grams, with an outline of 1.63 by 1.13 by 0.33 inches (LWH). The AMF Series converters weigh less than 36 grams, with an outline of 2.10 by 1.38 by 0.33 inches (LWH). The AMR Series converters weigh less than 68 grams, with an outline of 2.74 by 1.53 by 0.41 inches (LWH).
These converters are rated for operation over -55 to +125 °C. These converters are priced at $745 each for the AMA2805S/EM, $810 for the AMF2805S/EM and $925 for the AMR2805S/EM, all in 100-piece quantities. These products are subject to U.S. export laws and regulations.
