ATR2812D/CH

Manufacturer Part Number
ATR2812D/CH
Description
HYBRID-HIGH RELIABILITY DC/DC CONVERTER
Manufacturer
IRF [International Rectifier]
Datasheet
HYBRID-HIGH RELIABILITY
DC/DC CONVERTER
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 with
screening options. Refer to Part Number section. They
can be provided in a standard plug-in package for PC
mounting or in a flanged package for more severe
environments.
Extensive computer simulation using complex modeling
enables rapid design modification to be provided.
Contact IR Santa Clara with specific requirements.
Description
The ATR28XXD 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-704D input requirements, these devices
have nominal 28VDC inputs with ±12V and ±15V dual
outputs to satisfy a wide range of requirements. The
circuit design incorporates a pulse width modulated
single forward topology operating in the feed-forward
mode at a nominal switching frequency of 550KHz.
Input to output isolation is achieved through the use of
transformers in the forward and 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.
