AIF28515Q

The AIF28515 DC/DC converter features an internal EMI filter and four high performance outputs to obtain a moderate power density without derating over the full military temperature range. AIF28515 also offers input conditioning for operation from nominal +28 volt, MIL-STD 704A input power. This series incorporates Lambda Advanced Analog's proprietary magnetic pulse feedback technology providing optimum dynamic line and load regulation response. This feedback system samples the output voltage at the pulse width modulator fixed clock frequency, nominally 600 KHz. Undervoltage lockout, soft-start and load fault protection are provided on this device.

These AIF28515 converters are hermetically packaged in an enclosure of modest dimension, utilizing copper core pins to minimize resistive DC losses. These pin leads are each fabricated with Lambda Advanced Analog's rugged ceramic lead-to-package seal assuring long term hermeticity in the most harsh environments.

Manufactured in a facility fully qualified to MIL-PRF- 38534, these AIF28515 converters are available in several screening grades to satisfy a range of requirements. The HB grade is fully processed and screened to the class H requirement of MIL-PRF-38534, but does not have material element evaluated to the class H requirement. This grade is tested to meet the complete group "A" test specification over the full military temperature range without output power deration. Two additional grades with more modest screening are also available for use in less demanding applications of AIF28515. Variations in electrical, mechanical and screening can be accommodated.
