ADVANCED ANALOG
RADIATION TOLERANT
DC/DC CONVERTERS
Description
The AMF28XXS series of DC/DC converter modules
has been specifically designed for operation in moder-
ate radiation environments supplementing the higher
radiation performance available in the Advanced Ana-
log ART, ARH and G-Series converters. Environ-
ments 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 hard-
ness performance will be optimally served by the
AMF28XXS Series.

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 mechani-
cal security than traditional packages. Advanced
Analog’s rugged ceramic seal pins are used exclusively
in the package thereby assuring long term hermeticity.

The AMF28XXS has been designed for high density
using chip and wire hybrid technology that complies
with the class H requirements of MIL-PRF-38534. Fin-
ished product are fabricated in a facility fully qualified
to MIL-PRF-38534. The standard processing adopted
for the AMF28XXS meets the requirements of MIL-PRF-
38534 for class H but with enhanced screening steps
and includes element evaluation. Applicable generic
lot qualification test data including radiation perfor-
mance can be made available on request. Consult
Advanced Analog for special requirements.

Parameter guaranteed by line and load regulation tests.
Bandwidth guaranteed by design. Tested for 20 Hz to 2 MHz.
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
be guaranteed to the limit specified.

Load step transition time between 2 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 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
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 switch-
ing 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 telem-
etry). Advanced Analog 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 en-
able input is 10.0 +1 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.
