HYBRID - HIGH RELIABILITY
RADIATION TOLERANT
DC/DC CONVERTER
Description
The AMR28XXS 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
AMR28XXS Series.

The physical configuration of the AMR28XXS 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 secure
mechanical attachment than traditional radially leaded
packages. International Rectifier’s rugged ceramic seal
pins are used exclusively in the package thereby
assuring long term hermeticity.

n Standard Microcircuit Drawings Available
The AMR28XXS 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 DSCC
qualified processes. For available screening options,
refer to device screening table in the data sheet.Applicable

Parameter guaranteed by line and load regulation tests.
Bandwidth guaranteed by design. Tested for 20 KHz to 2.0 MHz.
Output voltage measured at load with remote sense leads connected across load.
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.

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.

Load step transition time between 2.0 and 10 microseconds.
Recovery time is measured from the initiation of the transient to where VOUT has returned to within ±1 % of VOUT at 50 percent load.
Input step transition time between 2.0 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.

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.
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). 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.
