Features
ATW
28V Input, Single Output
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.
Three standard temperature grades are offered. Refer
to Part Number section. These devices are provided in
a flanged package for secure mounting in severe
environments.
The ATW28XXS 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 input and are available
with single outputs at 5V,12V and 15V. 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.
