HYBRID-HIGH RELIABILITY
DC/DC CONVERTER
AFL120XXD SERIES
120V Input, Dual Output
Description
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 +28V or +270V inputs with
output power ranging from 80W to 120W. For applications
requiring higher output power, individual converters
can be operated in parallel. The internal current sharing
circuits assure equal current distribution among the
paralleled converters. This series incorporates International
Rectifier’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 550KHz. Multiple converters
can be synchronized to a system clock in the 500KHz
to 700KHz 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 International Rectifier’s
rugged ceramic lead-to-package seal assuring long
term hermeticity in the most harsh environments.

AFL120XXD Series
Internally, these ports differ slightly in their function. In use,
a low on Enable 1 completely shuts down all circuits in the
converter, while a low on Enable 2 shuts down the secondary
side while altering the controller duty cycle to near zero.
Externally, the use of either port is transparent to the user
save for minor differences in idle current. (See specification
table).
Synchronization of Multiple Converters
When operating multiple converters, system requirements
often dictate operation of the converters at a common
frequency. To accommodate this requirement, the AFL
series converters provide both a synchronization input and
output.
The sync input port permits synchronization of an AFL
converter to any compatible external frequency source
operating between 500KHz and 700KHz. This input signal
should be referenced to the input return and have a 10% to
90% duty cycle. Compatibility requires transition times less
than 100ns, maximum low level of +0.8V and a minimum
high level of +2.0V. The sync output of another converter
which has been designated as the master oscillator provides
a convenient frequency source for this mode of operation.
When external synchronization is not indicted, the sync in
pin should be left unconnected thereby permitting the
converter to operate at its’ own internally set frequency.
The sync output signal is a continuous pulse train set at
550 ± 50KHz, with a duty cycle of 15 ± 5.0%. This signal is
referenced to the input return and has been tailored to be
compatible with the AFL sync input port. Transition times
are less than 100ns and the low level output impedance is
less than 50. This signal is active when the DC input
voltage is within the specified operating range and the
converter is not inhibited. This synch output has adequate
drive reserve to synchronize at least five additional
converters. A typical synchronization connection option is
illustrated in Figure III.

Parallel Operation-Current and Stress Sharing
Figure III. illustrates the preferred connection scheme for
operation of a set of AFL converters with outputs operating
in parallel. Use of this connection permits equal current
sharing among the members of a set whose load current
exceeds the capacity of an individual AFL. An important
6
feature of the AFL series operating in the parallel mode is
that in addition to sharing the current, the stress induced by
temperature will also be shared. Thus if one member of a
paralleled set is operating at a higher case temperature, the
current it provides to the load will be reduced as
compensation for the temperature induced stress on that
device.
