FOD2712A

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.
