LAMBDA ADVANCED ANALOG INC. λλ
ATW2800S Series
Single Output, Hybrid - High Reliability
DC/DC Converter
DESCRIPTION
FEATURES
The ATW2800S 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-704 input requirements, these
devices have nominal 28VDC inputs with +5, +12V
and +15V single outputs.
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.
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 Number section. They are provided in
a flanged package for more severe enviroments.
Manufactured in a facility fully qualified to MIL-PRF-
38534, these converters are 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 (P.I.)
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.
Variations in electrical, mechanical
and screening can be accommodated.
