HYBRID - HIGH RELIABILITY
RADIATION TOLERANT
DC/DC CONVERTER
Description
The AMF28XXS 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 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 AMF28XXS Series.
AMF
Features
n 12 Watts Output Power
n Available in 3.3, 5, 7.5, 12 and 15 Volt Outputs
n 16 - 40 VDC Input Range (28 VDC Nominal)
n Low Input/Output Noise
n Total Ionizing Dose > 25KRads (Si)
The physical configuration of the AMF28XXS series
permits mounting directly to a heat dissipation 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.

Parameter guaranteed by line and load regulation tests.
Bandwidth guaranteed by design. Tested for 20Hz to 2.0MHz.
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. Therefore this Parameters shall

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 1.0 and 10 microseconds. Parameter guaranteed by design but not 100% tested.
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)
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). Interenational Rectifier 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.
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. The open circuit voltage of the
enable 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.
