ATR28XXS SERIES
28V Input, Single Output
HYBRID-HIGH RELIABILITY
DC/DC CONVERTERS
Description
The ATR28XXS 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 3.3V, 5V, 12V and
15V single 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.
ATR
Features
n 16 to 40 VDC Input Range (28 VDC Nominal)
n 3.3V, 5V, 12V and 15V Outputs Available
n Indefinite Short Circuit and Overload
Protection
n Up to 35 W/in3 Power Density
n 30 Watt Output Power Models
n Fast Loop Response for Superior Transient
Characteristics
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 feedback circuits.
n Operating Temperature Range from -55°C to
+125°C
n Popular Industry Standard Pin-Out
n Resistance Seam Welded Case for Superior
Long Term Hermeticity
Three standard temperature grades are offered with
screening options. Refer to Part Number section. These
devices can be provided in a standard plug-in package
for PC mounting or in a flanged package for more
severe environments.
n Ceramic Feed-thru Pins
n External Synchronization
n Efficiencies up to 84%
n Shutdown from External Signal
n Military Screening
These converters are manufactured in a facility certified
to MIL-PRF-38534. All processes used to manufacture
these converters have been qualified to enable
Advanced Analog to deliver compliant devices.
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 screening
but do not have class H element evaluation as required
by MIL-PRF-38534. Both grades are fully tested to
confirm operation 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
element evaluation. The non-suffix device is a low cost
limited temperature range option. Variations in electrical,
mechanical and screening can be accommodated.
Extensive computer simulation using complex
modeling enables rapid design modification to
be provided. Contact IR Santa Clara with specific
requirements.

Parameter guaranteed by line and load regulation tests.
Bandwidth guaranteed by design. Tested for 20 KHz to 2 MHz.
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 trigger the short circuit
protection and is the condition of maximum power dissipation.
7
8
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 percent of VOUT at 50 percent
load.
9
Input step transition time between 2 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 (pin 2) while power is applied to the input.

Parameter guaranteed by line and load regulation tests.
Bandwidth guaranteed by design. Tested for 20 KHz to 2 MHz.
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 IV.
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 condition of maximum power dissipation.

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 percent of VOUT at 50 percent l
load.

Input step transition time between 2 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 (pin2) while power is applied to the input.

Inhibit Function
Assuming that there is no forced air flow, the package
temperature rise above ambient (∆T) may be calculated
using the following expression:
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.
∆T = 80 A –0.7 P 0.85 (°C)
where A = the effective surface area in square inches
(Including heat sink if used),Pd = power dissipation in watts.
EMI Filter
An Optional EMI filter (AFC461)is available that will reduce
the input ripple current to levels below the limits imposed by
MIL-STD-461B CEO3.
The total surface area of the ATR package is 7.34 square
inches. If a worse case full load efficiency of 76% is as-
sumed, then the case temperature rise of an ATR2805S
can be calculated as follows:
Output Voltage Adjustment
The output voltage of the ATR2805S converter can be ad-
justed upward by connecting an appropriate resistor value
between the Positive Output (Pin 5) and the Positive Sense
(Pin 6) as shown in Table 1 below.

Hence, if TAMBIENT = +25°C, the DC/DC converter case
temperature will be approximately 159°C if no heat sink
or air flow is provided.
To calculate the heat sink area required to maintain a
specific case temperature rise, the above equation may
be manipulated as follows:

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. 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 sys-
tems. Advanced Analog permits synchronization of multiple
ATR28XX converters to match switching frequency of the
converter to the frequency of the system clock, thus elimi-
nating this type of noise.
