PRELIMINARY
AFL27003.3S Series
Single Output, Hybrid - High Reliability
DC/DC Converter
DESCRIPTION
FEATURES
The AFL Series of DC/DC converters feature high
power density with no derating over the full military
temperature range. This series is offered as part of
a complete family of converters providing single and
dual output voltages and operating from nominal
+28, +50, +120 or +270 volt inputs with output
power ranging from 80 to 120 watts. For
applications requiring higher output power, multiple
converters can be operated in parallel. The internal
current sharing circuits assure equal current
distribution among the paralleled converters. This
series incorporates Lambda Advanced Analog's
proprietary magnetic pulse feedback technology
providing optimum dynamic line and load regulation
response. This feedback system samples the output
voltage at the pulse width modulator fixed clock
frequency, nominally 550 KHz. Multiple converters
can be synchronized to a system clock in the 500
KHz to 700 KHz range or to the synchronization
output of one converter. Undervoltage lockout,
primary and secondary referenced inhibit, soft-start
and load fault protection are provided on all models.
These converters are hermetically packaged in two
enclosure variations, utilizing copper core pins to
minimize resistive DC losses. Three lead styles are
available, each fabricated with Lambda Advanced
Analog's rugged ceramic lead-to-package seal
assuring long term hermeticity in the most harsh
environments.
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 requirements, e.g., element
evaluation and Periodic Inspections (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. Contact
Lambda Advanced Analog for special requirements.
