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 -55ºC to 125°C. They expand the IR high-reliability (hi-rel) line of single- and dual-output voltage dc-dc converters operating from 28V to 270V input with output power ranging from 66W to 120W.
These devices are available with one of four screening levels to satisfy a variety 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.
Tiva Bussarakons, director, technical marketing at International Rectifier's Advanced Analog Group, said, “The AFL120 series converters offer one of the highest power density converters on the market. The new converters deliver their full-rated current under all normal operating conditions, including the full military temperature range. Multiple devices can be used in parallel with full current and stress sharing to increase capacity even further.”
The new converters incorporate proprietary magnetic pulse feedback technology, providing optimum dynamic line and load regulation response. This feedback system samples the output voltage at 550 kHz, the nominal pulse width modulator fixed clock frequency.
Manufactured in a facility fully qualified to MIL-PRF-38534, the converters are available in four screening grades. Variations in electrical, mechanical, and screening can be accommodated. Contact International Rectifier's Advanced Analog Group for special requirements at (408) 727-0500.
