HYBRID-HIGH RELIABILITY
DC/DC CONVERTER
ATO28XXT SERIES
28V Input, Triple Output
Description
The ATO28XXT Series of DC/DC converters feature
high power density and an extended temperature range
for use in military and industrial applications. Designed
to the nominal input requirements of MIL-STD-704D,
these devices have nominal 28VDC inputs with +5V
and ±12V or +5V and ±15V triple 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 250KHz. 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 feedback circuits.
Three standard temperature grades are offered. Refer
to Part Numbering section. They are provided in a
standard plug-in package for PC mounting or in a
flanged package for more severe environments.
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. Extensive computer simulation
using complex modeling enables modest design
modifications to be accommodated. Contact IR Santa
Clara with specific requirements.
