Features
AHE
28V Input, Dual Output
The AHE 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 ±5V, ±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 250KHz. 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. Contact IR Santa Clara for special
requirements.
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.
