FOD2743A, FOD2743B, FOD2743C Optically Isolated Error August 2008 FOD2743A, FOD2743B, FOD2743C Optically Isolated Error Amplifier • Optocoupler, precision reference and error amplifier in 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 • Low temperature coefficient 50ppm/°C max • FOD2743A tolerance FOD2743B tolerance 1% FOD2743C tolerance 2% • Power supplies regulation • DC to DC converters The FOD2743 Optically Isolated Amplifier consists of the popular KA431 precision programmable shunt reference and an optocoupler. The optocoupler is a gallium arsenide GaAs light emitting diode optically coupled to a silicon phototransistor. It comes in 3 grades of reference voltage tolerance = 2%, 1%, and The Current Transfer Ratio CTR ranges from 50% to 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 isolated AC to DC power supplies and dc/dc converters. When using the FOD2743, power supply designers can reduce the component count and save space in tightly packaged designs. The tight tolerance reference eliminates the need for adjustments in many applications. The device comes in an 8-pin dip white package.
