AFL270XXS Series
The AFL270XXS series converters incorporate a single
stage LC input filter whose elements dominate the input
load impedance characteristic during the turn-on sequence.
The input circuit is as shown in Figure 4.

A minimum voltage is required at the input of the converter
to initiate operation. This voltage is set to 150V
± 5.0V. To
preclude the possibility of noise or other variations at the
input falsely initiating and halting converter operation, a
hysteresis of approximately 10V is incorporated in this circuit.
Thus if the input voltage droops to 140V
± 5.0V, the converter
will shut down and remain inoperative until the input voltage
returns to
≈ 150V.
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 5. below. The range of adjustment and
corresponding range of resistance values can be
determined by use of the equation presented below.

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.

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 500
Ω.
By remaining within this specified range of values, completely
safe operation fully within normal component derating is
assured.
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
AFL270XXS 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 AFL270XXS 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. While operation in this condition is
not damaging to the device, not all performance parameters
will be met.
Typical performance data is graphically presented on the following
pages for selected parameters on a variety of AFL270XXS type
converters. The data presented was selected as representative
of more critical parameters and for general interest in typical
converter applications.
