ATW28XXD SERIES  
28V Input, Dual Output  
ADVANCED ANALOG  
HYBRID-HIGH RELIABILITY  
DC/DC CONVERTERS  
Description  
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.

Long Term Hermeticity  
Three standard temperature grades are offered. Refer  
to Part Number section for more severe environments.  
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.
