ADVANCED ANALOG
HIGH RELIABILITY
HYBRID DC/DC CONVERTERS
AFL50XXD SERIES
50V Input, Dual Output
The AFL Series of DC/DC converters feature high power
density with no derating over the full military tempera-
ture 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, individual converters can be operated in paral-
lel. The internal current sharing circuits assure equal
current distribution among the paralleled converters. This
series incorporates Advanced Analog’s proprietary mag-
netic pulse feedback technology providing optimum
dynamic line and load regulation response. This feed-
back system samples the output voltage at the pulse
width modulator fixed clock frequency, nominally 550
KHz. Multiple converters can be synchronized to a sys-
tem 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 mod-
els.
These converters are hermetically packaged in two en-
closure variations, utilizing copper core pins to mini-
mize resistive DC losses. Three lead styles are avail-
able, each fabricated with Advanced Analog’s rugged
ceramic lead-to-package seal assuring long term
hermeticity in the most harsh environments.

Features
AFL
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-H-
38534 for class H. The HB grade is fully processed and
screened to the class H requirement, may not neces-
sarily 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 com-
plete 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 screen-
ing can be accommodated. Contact Advanced
Analog for special requirements.
