PD - 94549B
ATR28XXS SERIES
28V Input, Single Output
HYBRID-HIGH RELIABILITY
DC/DC CONVERTER
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.
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.
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.
Manufactured in a facility fully qualified to MIL-PRF38534, 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.

Parameter guaranteed by line and load regulation tests.
Bandwidth guaranteed by design. Tested for 20KHz to 2.0MHz.
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.
5 Parameter shall be tested as part of design characterization and after design or process changes. There after parameters shall be
guaranteed to the limits specified in table I.
6 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 Load step transition time between 2.0µs and 10µs.
8 Recovery time is measured from the initiation of the transient to where VOUT has returned to within ±1.0% of V OUT at 50% load.
9 Input step transition time between 2.0µs and 10µs.
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.

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 2.0µs and 10µs.
Recovery time is measured from the initiation of the transient to where VOUT has returned to within ±1.0% of VOUT at 50% load.
Input step transition time between 2.0µs and 10µs.
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.

Application Information
Thermal Management
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
circuit voltage of the inhibit input is 11.5 ±1.0VDC.
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.
Output Voltage Adjustment
The output voltage of the ATR2805S converter can be
adjusted 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.

Device Synchronization
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
systems. International Rectifier permits synchronization of
multiple ATR28XX converters to match switching frequency
of the converter to the frequency of the system clock, thus
eliminating this type of noise.

∆T = 80 A –0.7 P 0.85 (°C)
where A = the effective surface area in square inches
(Including heat sink if used),P d = power dissipation in watts.
The total surface area of the ATR package is 7.34 square
inches. If a worse case full load efficiency of 76% is
assumed, then the case temperature rise of an ATR2805S
can be calculated as follows:

∆T = 80 (7.34)-0.7 (9.5)0.85 = 134°C
Hence, if T AMBIENT = +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:
⎡ ∆T ⎤
AHEATSINK = ⎢
0. 85 ⎥
⎢⎣ 80Pd

As an example, if a maximum case temperature rise of
50°C above ambient is required, then the required
effective heat sink area is:
