HYBRID - HIGH RELIABILITY
RADIATION TOLERANT
DC-DC CONVERTER
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
hermeticity.

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. 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. Variations to the standard
screening can be accommodated. Consult IR San
Jose for special requirements.

AMR28XXD Series
(28V Input, Dual Output)
Notes to Specifications
1. Parameter guaranteed by line and load regulation tests.
2. Up to 90 percent of full power is available from either output provided the total output does not exceed 30 watts.
3. Bandwidth guaranteed by design, Tested for 20 Hz to 2 MHz.
4. Load current split equally between +VOUT and –VOUT
.
5. 3 watt load on output under test. 3 watt to 27 watt load change on other output.
6. 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.

Application Information
Inhibit Function (Enable)
Connecting the inhibit input to input common will
cause the converter to shut down. 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.
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). International Rectifier 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.
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.
