PD-94689E AMF28XXXXS SERIES 28V Input, Single Output HYBRID-HIGH RELIABILITY RADIATION TOLERANT DC-DC CONVERTER AMF Description The AMF28XXXXS Series of DC-DC converter modules has been specifically designed for operation in moderate radiation environments supplementing the higher radiation performance available in the IR HiRel ART, ARH and G-Series converters. 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 AMF28XXXXS Series. The physical configuration of the AMF28XXXXS 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. IR HiRel rugged ceramic seal pins are used exclusively in the package thereby assuring long term hermeticity. The AMF28XXXXS has been designed for high density using chip and wire hybrid technology that complies with the class H requirements of MIL-PRF-38534. Manufactured in a facility fully qualified to MIL-PRF-38534, these converters are fabricated utilizing DLA qualified processes. For available screening options, refer to device screening table in the data sheet. Applicable generic lot qualification test data including radiation performance can be made available on request.

Parameter guaranteed by line and load regulation tests. 2. Bandwidth guaranteed by design. Tested for 20 Hz to 2.0MHz. 3. Capacitive value 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. 4. Parameter shall be tested as part of design characterization and after design or process changes. Thereafter, parameters shall be guaranteed to the limit specified. 5. Load step transition time between 2 and 10 microseconds. 6. Recovery time is measured from initiation of the transient to where VOUT has returned to within ±1% of VOUT at 50% load. 7. Input step transient time between 1 and 10 microseconds. 8. 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. 4 2016-05-16 AMF28XXXXS SERIES (28V Input, Single Output) Block Diagram EMI Filter 8 +Input +Output 3 Under-Voltage Detector Output Return 4 Primary Housekeeping Supply 1 Enable 6 Case Drive Pulse Width FB Modulator 2 Sync Input Error Amp & Ref CS Input Return 7 Application Information Inhibit Function (Enable) Device Synchronization Connecting the enable input (Pin 1) to input common (Pin 7) will cause the converter to shut down. It is recommended that the enable pin be driven by an open collector device capable of sinking at least 400 µA of current. Because it is internally pulled up, the open circuit voltage of the enable input is 10 +1.0 VDC. 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 AMF type converters to match switching frequency of the converter to the frequency of the system clock, thus eliminating this type of noise. 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.
