AFL50XXD SERIES
50V Input, Dual Output
HYBRID-HIGH RELIABILITY
DC/DC CONVERTER
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, +50V, +120V or +270 V
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 550
KHz. 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, softstart 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.

Circuit Operation and Application Information
The AFL series of converters employ a forward switched
mode converter topology. (refer to Figure I.) Operation of the
device is initiated when a DC voltage whose magnitude is
within the specified input limits is applied between pins 1 and
2. If pins 4 and 12 are enabled (at a logical 1 or open) the
primary bias supply will begin generating a regulated housekeeping voltage bringing the circuitry on the primary side of
the converter to life. Two power MOSFETs used to chop the
DC input voltage into a high frequency square wave, apply
this chopped voltage to the power transformer. As this switching is initiated, a voltage is impressed on a second winding of
the power transformer which is then rectified and applied to
the primary bias supply. When this occurs, the input voltage
is excluded from the bias voltage generator and the primary
bias voltage becomes internally generated.
The switched voltage impressed on the secondary output
transformer windings is rectified and filtered to provide the
positive and negative converter output voltages. An error
amplifier on the secondary side compares the positive output voltage to a precision reference and generates an error
signal proportional to the difference. This error signal is magnetically coupled through the feedback transformer into
the control section of the converter varying the pulse width of
the square wave signal driving the MOSFETs, narrowing the
pulse width if the output voltage is too high and widening it if it
is too low. These pulse width variations provide the necessary corrections to maintain the magnitude of output voltage
within its’ specified limits.
Because the primary and secondary sides are coupled by
magnetic elements, full isolation from input to output is
achieved.

Although incorporating several sophisticated and useful
ancillary features, basic operation of the AFL50XXD series
can be initiated by simply applying an input voltage to pins 1
and 2 and connecting the appropriate loads between pins 7,
8, and 9. Of course, operation of anyconverter with high
power density should not be attempted before secure attachment to an appropriate heat dissipator. (See Thermal
Considerations, page 7)
Inhibiting Converter Output (Enable)
As an alternative to application and removal of the DC voltage to the input, the user can control the converter output by
providing TTL compatible, positive logic signals to either of
two enable pins (pin 4 or 12). The distinction between these
two signal ports is that enable 1 (pin 4) is referenced to the
input return (pin 2) while enable 2 (pin 12) is referenced to the
output return (pin 8). Thus, the user has access to an inhibit
function on either side of the isolation barrier. Each port is
internally pulled “high” so that when not used, an open connection on both enable pins permits normal converter operation. When their use is desired, a logical “low” on either port
will shut the converter down.

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 required, 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 50Ω. This signal is active when the DC input
voltage is within the specified operating range and the
converter is not inhibited. The sync output has adequate
drive reserve to synchronize at least five additional converters.
A typical connection 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
compenstionfor the temperature induced stress on that
device.
www.irf.com
AFL50XXD Series
When operating in the shared mode, it is important that
symmetry of connection be maintained as an assurance of
optimum load sharing performance. Thus, converter outputs
should be connected to the load with equal lengths of wire of
the same gauge and sense leads from each converter should
be connected to a common physical point, preferably at the
load along with the converter output and return leads. All
converters in a paralleled set must have their share pins
connected together. This arrangement is diagrammatically
illustrated in Figure III. showing the outputs and return pins
connected at a star point which is located close as possible
to the load.
As a consequence of the topology utilized in the current
sharing circuit, the share pin may be used for other functions.
For applications requiring only a single converter, the voltage
appearing on the share pin may be used as a “current
monitor”. The share pin open circuit voltage is nominally
+1.00V at no load and increases linearly with increasing
output current to +2.20V at full load. Note that the current
we refer to here is the total device output current, that is, the
sum of the positive and negative output currents.
Thermal Considerations
Because of the incorporation of many innovative
technological concepts, the AFL series of converters is
capable of providing very high output power from a package
of very small volume. These magnitudes of power density
can only be obtained by combining high circuit efficiency
with effective methods of heat removal from the die junctions.
This requirement has been effectively addressed inside the
device; but when operating at maximum loads, a significant
amount of heat will be generated and this heat must be
conducted away from the case. To maintain the case
temperature at or below the specified maximum of 125°C,
this heat must be transferred by conduction to an
appropriate heat dissipater held in intimate contact with the
converter base-plate.
Since the effectiveness of this heat transfer is dependent on the
intimacy of the baseplate/heatsink interface, it is strongly
recommended that a high thermal conductivity heat transferring
medium is inserted between the baseplate and heatsink. The
material most frequently utilized at the factory during all testing
and burn-in processes is sold under the trade name of Sil-Pad®
4001 . This particular product is an insulator but electrically
conductive versions are also available. Use of these materials
assures maximum surface contact with the heat dissipater
thereby compensating for any minor surface variations. While
other available types of heat conductive materials and thermal
compounds provide similareffectiveness, these alternatives are
often less convenient and can be somewhat messy to use.
A conservative aid to estimating the total heat sink surface
area (A HEAT SINK ) required to set the maximum case
temperature rise (∆T) above ambient temperature is given
by the following expression:
.
⎧ ∆T ⎫ −143
⎬
− 3.0
A HEAT SINK ≈ ⎨
⎩ 80P 0.85 ⎭
where
∆T = Case temperature rise above ambient
⎫
⎧ 1
P = Device dissipation in Watts = POUT ⎨
− 1⎬
⎭
⎩ Eff
As an example, it is desired to maintain the case temperature
of an AFL5015D at ≤ +85°C while operating in an open area
whose ambient temperature is held at a constant +25°C;
then
∆T = 85 - 25 = 60°C
If the worst case full load efficiency for this device is 83% @
100W; then the power dissipation at full load is given by
⎧ 1
⎫
P = 100 • ⎨ − 1⎬ = 100 • (0.205) = 20.5W
⎩ .83 ⎭
and the required heat sink area is

⎧
⎫
A HEAT SINK = ⎨
0.85 ⎬
⎩ 80 • 20.5 ⎭
−1.43
− 3.0 = 56.3 in 2
Thus, a total heat sink surface area (including fins, if any) of
56 in2 in this example, would limit case rise to 60°C above
ambient. A flat aluminum plate, 0.25" thick and of approximate
dimension 4" by 7" (28 in2 per side) would suffice for this
application in a still air environment. Note that to meet the
criteria in this example, both sides of the plate require
unrestricted exposure to the +25°C ambient air.

Undervoltage Lockout
A minimum voltage is required at the input of the converter
to initiate operation. This voltage is set to 26.5 ± 1.5V. To
preclude the possibility of noise or other variations at the
input falsely initiating and halting converter operation, a
hysteresis of approximately 2.0V is incorporated in this
circuit. Thus if the input voltage droops to 24.5 ± 1.5V, the
converter will shut down and remain inoperative until the
input voltage returns to ≈ 25V.
Output Voltage Adjust
By use of the trim pin (10), the magnitude of output voltages
can be adjusted over a limited range in either a positive or
negative direction. Connecting a resistor between the trim
pin and either the output return or the positive output will
raise or lower the magnitude of output voltage. The span of
output voltage magnitude is restricted to the limits shown in
Table I.
Figure V. Connection for VOUT Adjustment
Note that the nominal magnitude of output voltage resides in
the middle of the table and the corresponding resistor value
is set to ∞. To set the magnitude above nominal, the adjust
resistor is connected to output return. To set the magnitude
below nominal, the adjust resistor is connected to the positive
output. (Refer to Figure V.)
For output voltage settings that are within the limits, but
between those presented in Table I, it is suggested that the
resistor values be determined empirically by selection or by
use of a variable resistor. The value thus determined can
then be replaced with a good quality fixed resistor for
permanent installation.
When use of the trim feature is elected, the user should be
aware that the temperature performance of the converter
output voltage will be affected by the temperature
performance of the resistor selected as the adjustment
element and therefore, the user is advised to employ
resistors with an very small temperature coefficient of
resistance.
