HYBRID-HIGH RELIABILITY
DC/DC CONVERTERS
PD-94557A
ATW28XXD SERIES
28V Input, Dual Output
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
operate with a nominal 28VDC inputs with ±12V and
±15V dual outputs to satisfy a wide range of requirements.
The circuit design incorporates a pulse width modulated
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
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 elements
in the feedback circuits.
Manufactured in a facility fully qualified to MIL-PRF-
38534, 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. Contact IR Santa Clara for special
requirements.
