El Segundo - Mar 04, 2004 International Rectifier, IR introduced the AMA Series (5W), AMF Series (12W), and AMR Series (30W) radiation-tolerant, high-reliability (hi-rel) DC-DC converters designed for extended operation in moderate radiation environments. The new converters are standard, off-the-shelf and proven units that solve the space industry's problems of lengthy design cycles and extensive design analysis requirements for custom units. The small size and low mass make them ideal for point-of-load regulators 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 25krads), 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. Bryan Rogers, Vice President of Sales and Marketing, Hi-Rel Products, said, "The established radiation tolerance and reliability heritage of our components and circuit designs are applied to the new AMA, AMF and AMR Series converters. System integrators and designers will save time by using these ready-made and proven modules rather than going with custom solutions." The new DC-DC converters have a 28V input, with standard output voltages of 3.3V, 5V, 12V and 15V for single output models, and plus/minus 5, plus/minus 12 and plus/minus 15V for dual output models. These converters are also available with both single and dual output. A separate MIL-STD-461C compliance filter is available. The AMA series converters weigh less than 32 grams, with an outline of 1.63"L x 1.13"W x 0.33"H. The AMF Series converters weigh less than 36 grams, with an outline of 2.10"L x 1.38"W x 0.33"H. The AMR Series converters weigh less than 68 grams, with an outline of 2.74"L x 1.53"W x 0.41"H. Operating temperature for each of the converters is -55 degrees C to 125 degrees C, and includes an on/off command. The devices have MIL-STD-461C, CE03 and CS01 compliance with an external filter.
