FOD2712A
Optically Isolated Error Amplifier
Features
■ Optocoupler, precision reference and error amplifier in
single package
Description
The FOD2712A Optically Isolated Amplifier consists of
the popular AZ431L precision programmable shunt ref-
1.240V ± 1% reference
CTR 100% to 200%
2,500V RMS isolation
UL approval E90700
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 1%. The current transfer ratio (CTR) ranges from
100% to 200%.
Applications
■ Power system for workstations
■ Telecom central office supply
■ Telecom bricks

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.
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.
