ATW
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 elements in
the feedback circuits.
Manufactured in a facility fully qualified to MIL-PRF-
38534, these converters are available in four screen-
ing grades to satisfy a wide range of requirements. The
CH grade is fully compliant to the requirements of MIL-
PRF-38534 for class H. The HB grade is processed
and screened to the class H requirement, but may not
necessarily meet all of the other MIL-PRF-38534 re-
quirements, e.g., element evaluation and Periodic In-
spection (PI) not required. Both grades are tested to
meet the complete group “A” test specification over the
full military temperature range without output power
deration. Two grades with a more limited screening
are also available for use in less demanding applica-
tions. Variations in electrical, mechanical and screen-
ing can be accommodated. Contact Advanced Analog
for special requirements.
Three standard temperature grades are offered. Refer
to Part Number section for more severe environments.
The ATW28XXD 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 op-
erate with a nominal 28 VDC inputs with ±12V and ±15V
dual outputs to satisfy a wide range of requirements.
The circuit design incorporates a pulse width modu-
lated 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 trans-
formers in the forward and feedback circuits.
