AFL50XXS SERIES

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 +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 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.

Figure II. Enable Input Equivalent Circuit

Circuit Operation and Application Information

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.

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 pin 4 is 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. A power MOSFET is used to chop the DC

input voltage into a high frequency square wave, applying

this chopped voltage to the power transformer at the nominal

converter switching frequency. Maintaining a DC voltage

within the specified operating range at the input assures

continuous generation of the primary bias voltage.

The switched voltage impressed on the secondary output

transformer winding is rectified and filtered to generate the

converter DC output voltage. An error amplifier on the

secondary side compares the 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 controller section of the

converter varying the pulse width of the square wave signal

driving the MOSFET, narrowing the width if the output voltage

is too high and widening it if it is too low, thereby regulating

the output voltage.

Remote Sensing

Connection of the + and - sense leads at a remotely located

load permits compensation for excessive resistance

between the converter output and the load when their

physical separation could cause undesirable voltage drop.

This connection allows regulation to the placard voltage at

of application. When the remote sensing feature is not used,

the sense lead should be connected to their respective

output terminals at the converter. Figure III. illustrates a

typical remotely sensed application.

Figure III. Preferred Connection for Parallel Operation

Synchronization of Multiple Converters

Parallel Operation-Current and Stress Sharing

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).

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

oper- ating 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 open (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. This output has adequate drive

reserve to synchronize at least five additional converters.

A typical connection is illustrated in Figure III.

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 sharing

among the members of a set whose load current exceeds

the capacity of an individual AFL. An important feaure 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.

If the worst case full load efficiency for this device is 83%;

then the power dissipation at full load is given by

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.

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.

In 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.

Thermal Considerations

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

similar effectiveness, these alternatives are often less

convenient and can be somewhat messy to use.

As an example, it is desired to maintain the case temperature

of an AFL5015S at ≤ +85°C while operating in an open area

whose ambient temperature is held at a constant +25°C;

then

Thus, a total heat sink surface area (including fins, if any) of

71 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 9" (36 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 ambient air.

Output Voltage Adjust

In addition to permitting close voltage regulation of remotely

located loads, it is possible to utilize the converter sense

pins to incrementally increase the output voltage over a

limited range. The adjustments made possible by this method

are intended as a means to “trim” the output to a voltage

setting for some particular application, but are not intended

to create an adjustable output converter. These output

voltage setting variations are obtained by connecting an

appropriate resistor value between the +sense and -sense

pins while connecting the -sense pin to the output return pin

as shown in Figure V. below. The range of adjustment and

corresponding range of resistance values can be determined

by use of the following equation.

Finding a resistor value for a particular output voltage, is

simply a matter of substituting the desired output voltage

and the nominal device voltage into the equation and solving

for the corresponding resistor value.

Note: Radj must be set ≥ 500Ω

Attempts to adjust the output voltage to a value greater than

120% of nominal should be avoided because of the potential

of exceeding internal component stress ratings and

subsequent operation to failure. Under no circumstance

should the external setting resistor be made less than 500W.

AFL50xxS

Examination of the equation relating output voltage and

resistor value reveals a special benefit of the circuit topology

utilized for remote sensing of output voltage in the AFL50XXS

series of converters. It is apparent that as the resistance

increases, the output voltage approaches the nominal set

value of the device. In fact the calculated limiting value of

output voltage as the adjusting resistor becomes very large

is ≈ 25mV above nominal device voltage.

The consequence is that if the +sense connection is

unintentionally broken, an AFL50XXS has a fail-safe output

voltage of Vout + 25mV, where the 25mV is independent of

the nominal output voltage. It can be further demonstrated

that in the event of both the + and - sense connections

being broken, the output will be limited to Vout + 440mV.

This 440mV is also essentially constant independent of the

nominal output voltage.

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.

AFL50XXS Series

General Application Information Table 1. Nominal Resistance of Cu Wire

The AFL50XXS series of converters are capable of

providing large transient currents to user loads on demand.

Because the nominal input voltage range in this series is

relatively low, the resulting input current demands will be

correspondingly large. It is important therefore, that the line

impedance be kept very low to prevent steady state and

transient input currents from degrading the supply voltage

between the voltage source and the converter input. In

applications requiring high static currents and large

transients, it is recommended that the input leads be made

of adequate size to minimize resistive losses, and that a

good quality capacitor of approximately 100µF be connected

directly across the input terminals to assure an adequately

low impedance at the input terminals. Table I relates nominal

resistance values and selected wire sizes.

Wire Size, AWG Resistance per ft

24 Ga 25.7 mΩ

22 Ga 16.2 mΩ

20 Ga 10.1 mΩ

18 Ga 6.4 mΩ

16 Ga 4.0 mΩ

14 Ga 2.5 mΩ

12 Ga 1.6 mΩ

Incorporation of a 100µF capacitor at the input terminals is

recommended as compensation for the dynamic effects

of the parasitic resistance of the input cable reacting with

the complex impedance of the converter input, and to

provide an energy reservoir for transient input current

requirements.
