International Rectifier Corp. (IR, El Segundo, CA) introduced two hermetically sealed, 120V input, dc/dc converters that handle up to 84W/in³ power density, and deliver up to 80 percent efficiency. The new converters are designed for military and other high-reliability systems, including instrumentation and experiments aboard Space Station Freedom.
The new AFL12005S delivers 16A at 5V output, and the AFL1203R3S delivers 20A at 3.3V output. The AFL12005S handles up to 25 percent more power at 5V than the closest competing device, according to IR. The AFL1203R3S is claimed to be the industry’s first hermetically sealed, 120V input, 3.3V output, dc/dc converter in a 3in x 1.5in x 0.38in package. The AFL120 Series converters are fully functional, self-contained, dc/dc converters with an input range from 80V to 160V, characterized and rated over the full military temperature range of -55°C to +125°C.
The devices are available with one of four screening levels to satisfy a wide range of requirements. The CH grade is fully compliant to the requirements of MIL-PRF-38534 for class H and is tested to meet the complete group "A" test specification over the full military temperature range without output power de-rating. The converters incorporate proprietary magnetic-pulse feedback technology, providing optimum dynamic line and load-regulation response.
The new devices are now available. Pricing begins at $970 each for the AFL12005SX/ES or AFL1203R3SX/ES in 100-unit quantities.
