Please note: As part of the Fairchild Semiconductor integration, some of the Fairchild orderable part numbers
will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor
product management systems do not have the ability to manage part nomenclature that utilizes an underscore
(_), the underscore (_) in the Fairchild part numbers will be changed to a dash (-). This document may contain
device numbers with an underscore (_). Please check the ON Semiconductor website to verify the updated
device numbers. The most current and up-to-date ordering information can be found at www.onsemi.com. Please

Optically Isolated Error Amplifier
Features
Description
■ Optocoupler, precision reference and error amplifier in
The FOD2712A Optically Isolated Amplifier consists of
the popular AZ431L precision programmable shunt ref-
erence and an optocoupler. The optocoupler is a gallium
arsenide (GaAs) light emitting diode optically coupled to
a silicon phototransistor. The reference voltage toler-
ance is 1ꢀ. The current transfer ratio (CTR) ranges from
100ꢀ to 200ꢀ.
single package
■ 1.240V 1ꢀ reference
■ CTR 100ꢀ to 200ꢀ
■ 2,500V RMS isolation
■ UL approval E90700
It is primarily intended for use as the error amplifier/
reference voltage/optocoupler function in isolated AC to
DC power supplies and dc/dc converters.
Applications
■ Power system for workstations
■ Telecom central office supply
■ Telecom bricks
When using the FOD2712A, power supply designers can
reduce the component count and save space in tightly
packaged designs. The tight tolerance reference elimi-
nates the need for adjustments in many applications.
The device comes in a compact 8-pin small outline
package.

The FOD2712A
Compensation
The FOD2712A is an optically isolated error amplifier. It
incorporates three of the most common elements neces-
sary to make an isolated power supply, a reference volt-
age, an error amplifier, and an optocoupler. It is
functionally equivalent to the popular AZ431L shunt volt-
age regulator plus the CNY17F-3 optocoupler.
The compensation pin of the FOD2712A provides the
opportunity for the designer to design the frequency
response of the converter. A compensation network may
be placed between the COMP pin and the FB pin. In typ-
ical low-bandwidth systems, a 0.1µF capacitor may be
used. For converters with more stringent requirements, a
network should be designed based on measurements of
the system’s loop. An excellent reference for this pro-
cess may be found in “Practical Design of Power
Supplies” by Ron Lenk, IEEE Press, 1998.
Powering the Secondary Side
The LED pin in the FOD2712A powers the secondary
side, and in particular provides the current to run the
LED. The actual structure of the FOD2712A dictates the
minimum voltage that can be applied to the LED pin: The
error amplifier output has a minimum of the reference
voltage, and the LED is in series with that. Minimum volt-
age applied to the LED pin is thus 1.24V + 1.5V = 2.74V.
This voltage can be generated either directly from the
output of the converter, or else from a slaved secondary
winding. The secondary winding will not affect regula-
tion, as the input to the FB pin may still be taken from the
output winding.
Secondary Ground
The GND pin should be connected to the secondary
ground of the converter.
No Connect Pins
The NC pins have no internal connection. They should
not have any connection to the secondary side, as this
may compromise the isolation structure.
The LED pin needs to be fed through a current limiting
resistor. The value of the resistor sets the amount of
current through the LED, and thus must be carefully
selected in conjunction with the selection of the primary
side resistor.
Photo-Transistor
The Photo-transistor is the output of the FOD2712A. In a
normal configuration the collector will be attached to a
pull-up resistor and the emitter grounded. There is no
base connection necessary.
The value of the pull-up resistor, and the current limiting
resistor feeding the LED, must be carefully selected to
account for voltage range accepted by the PWM IC, and
for the variation in current transfer ratio (CTR) of the
opto-isolator itself.
Feedback
Output voltage of a converter is determined by selecting
a resistor divider from the regulated output to the FB pin.
The FOD2712A attempts to regulate its FB pin to the ref-
erence voltage, 1.24V. The ratio of the two resistors
should thus be:
Example: The voltage feeding the LED pins is +12V, the
voltage feeding the collector pull-up is +10V, and the
PWM IC is the Fairchild KA1H0680, which has a 5V ref-
erence. If we select a 10KΩ resistor for the LED, the
maximum current the LED can see is:
RTOP
------------------------- = -------------- – 1
RBOTTOM VREF
VOUT
The absolute value of the top resistor is set by the input
offset current of 0.8µA. To achieve 1ꢀ accuracy, the
(12V–2.74V) /10KΩ = 926µA.
resistance of R
should be:
TOP
The CTR of the opto-isolator is a minimum of 100ꢀ, and
so the minimum collector current of the photo-transistor
when the diode is full on is also 926µA. The collector
resistor must thus be such that:
V
OUT – 1.24
------------------------------- > 80 µA
RTOP
10V – 5V
----------------------------------- < 926 µA or RCOLLECTOR > 5.4KΩ;
RCOLLECTOR
select 10KΩ to allow some margin.
