28V Input, Dual Output
ADVANCED ANALOG
HYBRID-HIGH RELIABILITY
DC/DC CONVERTERS
Description
The ATW28XXD Series of DC/DC converters feature
high power density and an extended temperature range
for use in military and industrial applications. Designed
to MIL-STD-704 input requirements, these devices op-
erate with a nominal 28 VDC inputs with ±12V and ±15V
dual outputs to satisfy a wide range of requirements.
The circuit design incorporates a pulse width modu-
lated push-pull topology operating in the feed-forward
mode at a nominal switching frequency of 270KHz. Input
to output isolation is achieved through the use of trans-
formers in the forward and feedback circuits.

Three standard temperature grades are offered. Refer
to Part Number section for more severe environments.
Manufactured in a facility fully qualified to MIL-PRF-
38534, these converters are available in four screen-
ing grades to satisfy a wide range of requirements. The
CH grade is fully compliant to the requirements of MIL-
PRF-38534 for class H. The HB grade is processed
and screened to the class H requirement, but may not
necessarily meet all of the other MIL-PRF-38534 re-
quirements, e.g., element evaluation and Periodic In-
spection (PI) not required. Both grades are tested to
meet the complete group “A” test specification over the
full military temperature range without output power
deration. Two grades with a more limited screening
are also available for use in less demanding applica-
tions. Variations in electrical, mechanical and screen-
ing can be accommodated. Contact Advanced Analog
for special requirements.

Parameter guaranteed by line, load and cross regulation tests.
Up to 90% of full power is available from either output provided the total output does not exceed 30W.
Bandwidth guaranteed by design. Tested for 20KHz to 2MHz.
Load current split equally between +VOUT and –VOUT
.
Three-watt load on output under test, 3 watt to 27 watt load change on other output.
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.
Thereafter, parameters shall be guaranteed to the limits specified in Table I.
An overload is that condition with a load in excess of the rated load but less than that necessary to
trigger the short circuit protection and is the condition of maximum power dissipation.
Load step transition time between 2 and 10 microseconds.

10 Recovery time is measured from the initiation of the transient to where VOUT has returned to within ±1
percent of VOUT at 50 percent load.
11 Input step transition time between 2 and 10 microseconds.
12 Turn-on delay time measurement is for either a step application of power at the input or the removal of
ground signal from the inhibit pin (pin 8) while power is applied to the input.

Application Information
Inhibit Function
Connecting the inhibit input (Pin 8) to input common (Pin 10)
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 400µA of current. The open cir-
cuit voltage of the inhibit input is 11.5 ±1 VDC.
The user should be aware that the synchronization sys-
tem is fail-safe; that is, the slaves will continue operating
should the master frequency be interrupted for any rea-
son. The layout must be such that the synchronization
output (pin 2) of the master device is connected to the
synchronization input (pin 2) of each slave device. It is
advisable to keep this run short to minimize the possibil-
ity of radiating the 250KHz switching frequency.
EMI Filter
An optional external EMI filter (AFC461) is available that will
reduce the input ripple current to levels below the limits
imposed by MIL-STD-461B CEO3.
The appropriate parts must be ordered to utilize this fea-
ture. After selecting the converters required for the sys-
tem, a ‘MSTR’ suffix is added for the master converter
part number and a ‘SLV’ suffix is added for slave part
number. See Part Number section.
Device Synchronization
Whenever multiple DC/DC converters are utilized in a single
system, significant low frequency noise may be generated
due to the slight differences in the switching frequencies of
the converters (beat frequency noise). Because of the low
frequency nature of this noise (typically less than 10KHz), it
is difficult to filter out and may interfere with proper operation
of sensitive systems (communications, radar or telemetry).
Advanced Analog offers an option, which allows synchroni-
zation of multiple AHE/ATW type converters, thus eliminat-
ing this type of noise.

To take advantage of this capability, the system designer
must assign one of the converters as the master. Then, by
definition, the remaining converters become slaves and will
operate at the masters’ switching frequency.
