IR Unveils AMA, AMF and AMR DC-DC Converters

International Rectifier Corp. (IR, El Segundo, CA) introduced its AMA Series (5 W), AMF Series (12 W) and AMR Series (30 W) of radiation-tolerant, high-reliability, dc-dc converters designed for extended operation in moderate radiation environments. The new converters are standard, off-the-shelf units suitable for point-of-load regulators or as a building block in a power system for low earth orbit satellites and launch vehicles.

The AMA, AMF and AMR converters have a 28 V input, with standard output voltages of 3.3 V, 5 V, 12 V and 15 V for single-output models, and ±5 V, ±12 V and ±15 V for dual-output models. The AMA Series weigh <32 g, with an outline of 1.63 in x 1.13 in x 0.33 in. The AMF Series weigh <36 g, with an outline of 2.10 in x 1.38 in x 0.33 in. The AMR Series weigh <68 g, with an outline of 2.74 in x 1.53 in x 0.41 in. The operating temperature range for each of the converters is -55 °C to +125 °C, and includes an on/off command. The devices have MIL-STD-461C, CE03 and CS01 compliance with an external filter.

Pricing is $745 each for the AMA2805S/EM, $810 each for the AMF2805S/EM and $925 each for the AMR2805S/EM in 100-piece quantities.
