The advanced feedback design provides fast loop re-
sponse for superior line and load transient character-
istics and offers greater reliability and radiation toler-
ance than devices incorporating optical feedback cir-
cuits.
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 en-
vironments.
These converters are manufactured in a facility certi-
fied to MIL-PRF-38534. All processes used to manu-
facture these converters have been qualified to enable
Advanced Analog to deliver compliant devices.
Two screening grades are available to satisfy a wide
range of requirements. The CH grade converters are
fully compliant to MIL-PRF-38534 for class H. The HB
grade converters are processed to full class H screen-
ing but do not have class H element evaluation as re-
quired by MIL-PRF-38534. Both grades are fully tested
and operate over the full military temperature range
without derating of output power. Variations in electri-
cal, mechanical and screening can be accommodated.
Extensive computer simulation using complex
modeling enables rapid design modification to
be provided. Contact Advanced Analog with spe-
cific requirements.
The AHE28XXS 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
single outputs to satisfy a wide range of requirements.
The circuit design incorporates a pulse width modu-
lated 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.
