Optically Isolated Error Amplifier

Features

Description

■ Optocoupler, precision reference and error amplifier in

The FOD2743 Optically Isolated Amplifier consists of the

popular KA431 precision programmable shunt reference

and an optocoupler. The optocoupler is a gallium ars-

enide (GaAs) light emitting diode optically coupled to a

silicon phototransistor. It comes in 3 grades of reference

voltage tolerance = 2%, 1%, and 0.5%.

a single package

■ 2.5V reference

■ CTR 50% to 100% at 1mA

■ 5,000V RMS isolation

■ UL approval E90700, Vol. 2

CSA approval 1296837

VDE approval pending

BSI approval pending

The Current Transfer Ratio (CTR) ranges from 50% to

100%. It also has an outstanding temperature coefficient

of 50 ppm/°C. It is primarily intended for use as the error

amplifier/reference voltage/optocoupler function in iso-

lated AC to DC power supplies and dc/dc converters.

■ Low temperature coefficient 50ppm/°C max

■ FOD2743A: tolerance 0.5%

FOD2743B: tolerance 1%

FOD2743C: tolerance 2%

When using the FOD2743, 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 an 8-pin dip white package.

Applications

■ Power supplies regulation

■ DC to DC converters
