HYBRID-HIGH RELIABILITY
RADIATION TOLERANT
DC-DC CONVERTER
AMA
Description
The AMA28XXD 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 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 AMA28XXD Series.
The physical configuration of the AMA28XXD 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 hermeticity.

Applicable to positive and negative outputs..
Maximum combined output is 5.0 watts. 4.0 watts (max.) is available from either output (80%).
Load current split equally between +VOUT and –VOUT.
1.0 watt load on output under test, 1.0 watt to 4.0 watt load change on other output.
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.
Parameter shall be tested as part of design characterization and after design or process changes. Thereafter, parameters shall be
guaranteed to the limit specified.
Load step transition time between 2 and 10 microseconds.
Recovery time is measured from initiation of the transient to where VOUT has returned to within ±1% of VOUT at 50% load.
Input step transient time between 1 and 10 microseconds.
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.

Thermal Considerations
Connecting the inhibit input (Pin 5) 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 mA of current. The open
circuit voltage of the inhibit input is 10 +1.0 VDC
Irrespective of the fact that the AMA28XXD series of
converters are relatively low power devices and are
designed to provide efficient voltage conversion, there
will be some heat generated during normal operation.
To avoid a continuous thermal rise that may eventually
exceed the maximum case temperature rating and to
maintain a safe operating environment for the internal
components, these converters should be attached to a
heat conducting surface allowing a continuous flow of
the heat away from the base plate. This becomes more
important when operating in the near vacuum
environment of space which provides no alternate heat
radiating path.
EMI Filter
An optional EMI filter is available (ASF461 or AFH461) will
reduce the input ripple current to levels below the limits
imposed by MIL-STD-461 CE03.

Notes:
 Best commercial practice.
 Devices with ”/CH” suffix is a DLA class H compliant without radiation performance. No suffix is a radiation rated
device but not available as a DLA qualified SMD per MIL-PRF-38534.
 Any Engineering Model (EM) build with the “EM” Suffix shall only be form, fit and functional equivalent to its
Flight Model (FM) counterpart, and it may not meet the radiation performance. The EM Model shall not be expected
comply with MIL-PRF-38534 flight quality/workmanship standards, and configuration control. An EM build may use
electrical equivalent commercial grade components. IR HiRel will provide a list of non-compliance items upon request.
