PD-94690E AMR28XXD SERIES 28V Input, Dual Output HYBRID-HIGH RELIABILITY RADIATION TOLERANT DC-DC CONVERTER AMR Description The AMR28XXD Series of DC-DC converter modules has been specifically designed for operation in moderate radiation environments supplementing the higher radiation performance available in the International Rectifier ART2815T converter series. Environments presented to space vehicles operating in low earth orbits, launch boosters, orbiting space stations and similar applications requiring a low power, high performance converter with moderate radiation hardness performance will be optimally served by the AMR28XXD series. The physical configuration of the AMR28XXD Series permits mounting directly to a heat conduction surface without the necessity of signal leads penetrating the heat sink surface. This package configuration permits greater independence in mounting and more mechanical security than traditional packages. International Rectifier’s rugged ceramic seal pins are used exclusively in the package thereby assuring long term hermetically Features 30 Watts Output Power Available in ± 5, ±12 and ±15 Volt Outputs 16- 40 VDC Input Range (28 VDC Nominal) Total Ionizing Dose > 25 kRads(Si) SEE Hardened to LET up to 60 MeVcm2/mg -55°C to +125°C Operating Range Indefinite Short Circuit Protection External Synchronization Shutdown from External Signal Flexible Mounting Fully Isolated - Input to Output and to Case Complimentary EMI Filter Available Electrical Performance Similar to ATR28XXD Series The AMR28XXD has been designed for high density using chip and wire hybrid technology that complies with class H requirement of MIL-PRF-38534. Manufactured in a facility fully qualified to MIL-PRF-38534, these converters are fabricated utilizing DLA Land and Maritime qualified processes.

Parameter guaranteed by line and load regulation tests. Up to 90 percent of full power is available from either output provided the total output does not exceed 30 watts. Bandwidth guaranteed by design, Tested for 20 Hz to 2 MHz. Load current split equally between +VOUT and –VOUT. 3 watt load on output under test. 3 watt to 27 watt load change on other output. Capacitive load may be any value from 0 to the maximum limit without compromising DC performance. A capacitive load in excess of the maximum limit will not disturb loop stability but may interfere with the operation of the load fault detection circuitry, appearing as a short circuit during turn-on. 7. Parameter shall be tested as part of design characterization and after design or process changes, Parameters shall be guaranteed to the limit specified in Electrical Specifications 8. Load step transition time between 2 and 10 microseconds. 9. Recovery time is measured from initiation of the transient to where Vout has returned to within ±1% of Vout at 50% load. 10. Input step transient time between 2 and 10 microseconds. 11. Turn-on delay time measurement is for either a step application of power at the input or the removal of a ground signal from the inhibit pin while power is applied to the input.

It is recommended that the inhibit pin be driven by an open collector device capable of sinking at least 400 µA of current. The open circuit voltage of the inhibit input is 10 ±1.0 VDC. EMI Filter An optional EMI filter is available (AFH461) that will reduce the input ripple current to levels below the limits imposed by MIL-STD-461 CE03. 5 Device Synchronization When multiple DC-DC converters are utilized in a single system, significant low frequency noise may be generated due to a small difference in the switching frequency of the converters (beat frequency noise). Because of the low frequency nature of this noise (typically less than 10 kHz), it is difficult to filter out and may interfere with proper operation of sensitive systems (communication, radar or telemetry). IR HiRel provides synchronization of multiple AMR type converters to match switching frequency of the converter to the frequency of the system clock, thus eliminating this type of noise. 2016-06-29 AMR28XXD SERIES (28V Input, Dual Output) Mechanical Outline 0.220 Ø 0.125 3 PLACES 0.050 1 10 2 9 R 0.15 TYP.
