Features
ATW
28V Input, 300V Single Output
The advanced feedback design provides fast loop
response for superior line and load transient
characteristics and offers greater reliability than
devices incorporating optical feedback circuits.
The ATW28300S DC-DC converter features high
power density and an extended temperature range
for use in military and industrial applications.
Designed to MIL-STD-704D input requirements, this
device operates with a nominal 28VDC input with an
adjustable output of 150 to 300V via external
potentiometer. 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.
HYBRID HIGH-RELIABILITY
DC-DC CONVERTER
Manufactured in a facility fully qualified to MIL-PRF-
38534, this converter is available in four screening
grades to satisfy a wide range of requirements. The
CH grade is fully compliant to the requirements of
MIL-PRF-38534 for class H. The HB grade is
processed and screened to the class H requirement,
but may not necessarily meet all of the other MIL-
PRF-38534 requirements, e.g., element evaluation
and periodic inspection not required. Both grades
are tested to meet the complete group “A” test
specification over the full military temperature range
without output power deration. Two grades with more
limited screening are also available for use in less
demanding applications. For screening options, refer
to device screening table. Variations in electrical,
mechanical and screening can be accommodated.
