ATW28XXS SERIES
28V Input, Single Output
HYBRID-HIGH RELIABILITY
DC/DC CONVERTER
Description
ATW
The ATW28XXS 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
operate with a nominal 28VDC input and are available
with single outputs at 5V,12V and 15V. The circuit design
incorporates a pulse width modulated 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 transformers in
the forward and feedback circuits.
Features
n 19V to 40VDC Input Range (28VDC Nominal)
n 30W Output Power
n Indefinite Short Circuit and Overload Protection
n 22.8W/in3 Power Density
n Fast Loop Response for Superior Transient
Characteristics
n Operating Temperature Range from -55°C to
+125°C Available
The advanced feedback design provides fast loop
response for superior line and load transient
characteristics and offers greater reliability and radiation
tolerance than devices incorporating optical elements
in the feedback circuits.
n Popular Industry Standard Pin-Out
n Resistance Seam Welded Case for Superior
Long Term Hermeticity
n Efficiencies up to 83%
n Shutdown from External Signal
n Military Screening
Three standard temperature grades are offered. Refer
to Part Number section. These devices are provided in
a flanged package for secure mounting in severe
environments.
n 250,000 hour MTBF at 85°C
n Standard Microcircuit Drawings Available
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.
Variations in electrical, mechanical and screening can
be accommodated. Contact IR Santa Clara for special
requirements.

Parameter guaranteed by line and load regulation tests.

Above +125°C case, derate output power linearly to 0 at +135°C.
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.
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

Recovery time is measured from the initiation of the transient to where VOUT has returned to within ±1.0% of VOUT at 50% load.

ground signal from the inhibit pin (pin 1) while power is applied to the input is unlimited.

Application Information
Inhibit Function (Enable)
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.
Connecting the inhibit input (Pin 2) 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
circuit voltage of the inhibit input is 11.5 ±1.0VDC.
The user should be aware that the synchronization
system is fail-safe; that is, the slaves will continue
operating should the master frequency be interrupted for
any reason. The layout must be such that the
synchronization output (pin 8) of the master device is
connected to the synchronization input (pin 8) of each
slave device. It is advisable to keep this run short to
minimize the possibility of radiating the 250KHz switching
frequency.
EMI Filter
An optional EMI filter (AFC461) will reduce the input ripple
current to levels below the limits imposed by MIL-STD-461
CEO3.
Remote Sense (ATW2805S only)
Better than 0.1% line and load regulation (case temperature
constant) are typical when the remote sense leads are used.
If the remote sense leads are left unconnected, then the
output voltage (measured at pins 4 and 5) will rise to
approximately 5.4VDC. If the remote sense leads are shorted
together, the output voltage may rise above 10VDC
depending on load, possibly damaging both the converter
and load.
The appropriate parts must be ordered to utilize this
feature. After selecting the converters required for the
system, 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.

ATW28xxS
Whenever multiple DC/DC converters are utilized in a single
system, significant low frequency noise may be generated
due to the sight 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).
International Rectifier offers an option, which provides
synchronization of multiple AHE/ATW type converters, thus
eliminating this type of noise.
