ATR28XXD SERIES
28V Input, Dual Output
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.
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.
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.
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.
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

Notes to Specifications
1. Above +125°C case temperature, derate output power linearly to 0 at +135°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
0.8V Max, 11.5V Max
