ATR28XXD SERIES
28V Input, Dual Output
ADVANCED ANALOG
HYBRID-HIGH RELIABILITY
DC/DC CONVERTERS
Description
The ATR28XXD 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-704D input requirements, these devices
have nominal 28VDC inputs with ±12V and ±15V dual
outputs to satisfy a wide range of requirements. The
circuit design incorporates a pulse width modulated
single forward topology operating in the feed-forward
mode at a nominal switching frequency of 550KHz.
Input to output isolation is achieved through the use of
transformers in the forward and feedback circuits.

Features
n 16 to 40 VDC Input Range (28 VDC Nominal)
±12V and ±15V Outputs Available
n
n Indefinite Short Circuit and Overload
Protection
n 35 W/in3 Power Density
n 30 Watt Output Power
The advanced feedback design provides fast loop re-
sponse for superior line and load transient character-
istics and offers greater reliability and radiation toler-
ance than devices incorporating optical feedback cir-
cuits.
n Fast Loop Response for Superior Transient
Characteristics
n Operating Temperature Range from -55°C to
+125°C
Three standard temperature grades are offered with
screening options. Refer to Part Number section. They
can be provided in a standard plug-in package for PC
mounting or in a flanged package for more severe en-
vironments.
n Popular Industry Standard Pin-Out
n Resistance Seam Welded Case for Superior
Long Term Hermeticity
n Ceramic Feed-thru Pins
n External Synchronization
n High Efficiency
These converters are manufactured in a facility certi-
fied to MIL-PRF-38534. All processes used to manu-
facture these converters have been qualified to enable
Advanced Analog to deliver compliant devices.
n Shutdown from External Signal
n Military Screening
Four screening grades are available to satisfy a wide
range of requirements. The CH grade converters are
fully compliant to MIL-PRF-38534 for class H. The HB
grade converters are processed to full class H screen-
ing but do not have class H element evaluation as re-
quired by MIL-PRF-38534. Both grades are fully tested
and operate over the full military temperature range
without derating of output power. The ES version is a
full temperature device without the full class H or ele-
ment evaluation. The non-suffix device is a low cost
limited temperature range option. Variations in
electrical, mechanical and screening can be ac-
commodated.
Extensive computer simulation using complex
modeling enables rapid design modification to
be provided. Contact Advanced Analog with spe-
cific requirements.

1. Above +85°C case temperature, derate output power linearly to 0 at +115°C case.
2. Recovery time is measured from the initiation of the input transient to where VOUT has returned to within ±1% of VOUT at 50% load.
3. Turn-on delay time measurement is for either an application of power at the input or a signal at the inhibit pin.
4. Load current split equally between +VOUT and –VOUT
.
5. Up to 90% of Full Power is available from either output provided. The total power output does not exceed 30 watts.
6. 3W load on output under test, 3W to 27W on other output.
7. Sync. Input signal: VIL = -0.5V Min, VIN = 2.5V Min, 10% to 90% duty cycle,

Thermal Management
Application Information
Assuming that there is no forced air flow, the package
temperature rise above ambient (∆T) may be calculated
using the following expression:
Inhibit Function
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 cir-
cuit voltage of the inhibit input is 11.5 ±1 VDC.
∆Τ = 80 A –0.7 Pd 0.85 (°C)
(1)
where A = the effective surface area in square inhes(in-
cluding heat sink if used), Pd = power dissipation in watts.
EMI Filter
The total surface area of the ATR standard package is
7.34 square inches. If a worse case full load efficiency of
78% is assumed, then the case temperature rise can be
calculated as follows:
An EMI filter (AFC461), available as an option, will reduce
the input ripple current to levels below the limits imposed by
MIL-STD-461B CEO3.

Device Synchronization
Eff
78
Whenever multiple DC/DC converters are utilized in a single
system, significant low frequency noise may be generated
due to slight difference in the switching frequencies of the
converters (beat frequency noise). Because of the low fre-
quency 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).
The Advanced Analog ATR28xx converters provide a syn-
chronizing input permitting synchronization of multiple con-
verters to the frequency of the users system clock, thereby
minimizing this type of noise.
and
∆Τ = 80 (7.34) –0.7 (8.5)0.85 = 122°C
Hence, if TAMBIENT = +25°C, the DC/DC converter case
temperature will be approximately 147°C if no heat sink
or air flow is provided.
To calculate the heat sink area required to maintain a
specific case temperature rise, equation (1) may be
manipulated as follows:
−1.43
∆T
AHEATSINK
=
− APKG
0.85
80Pd
As an example, if it is desired to limit the case tempera-
ture rise to a maximum of 50°C above ambient, the
required effective heat sink area is:
−1.43
50
80(8.5)0.85
