AMF28XXD SERIES
28V Input, Dual Output
ADVANCED ANALOG
RADIATION TOLERANT
DC/DC CONVERTERS
Description
The AMF28XXD 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 ART2815T converter series. Environments pre-
sented 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 perfor-
mance will be optimally served by the AMF28XXD se-
ries.

The physical configuration of the AMF28XXD 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 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 AMF28XXD 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 AMF28XXD 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.

Notes to Specifications
1. Applicable to positive and negative outputs.
2. Maximum combined output is 12 watts. 10.8 watts (max.) is available from either output (90%).
3. Load current split equally between +VOUT and VOUT
.
4. 1.2 watt load on output under test, 1.2 watt to 10.8 watt load change on other output.
5. 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.
6. Parameter shall be tested as part of design characterization and after design or process changes. Thereafter,
parameters shall be guaranteed to the limit specified.
7. Load step transition time between 2 and 10 microseconds.
8. Recovery time is measured from initiation of the transient to where Vout has returned to within ±1% of Vout at
50% load.
9. Input step transient time between 1 and 10 microseconds.
10. 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
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. If the user chooses not to use the inhibit
function, it may be left open and the converter will
function normally. Because it is internally pulled up,
the open circuit voltage of the inhibit input is 10.0
+1VDC.
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.
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.
