Fairchild FOD2743B Manuals

FOD2743A, FOD2743B, FOD2743C Optically Isolated Error Amplifier is a single-chip device that combines an optocoupler, a precision programmable shunt reference and an error amplifier. It features a 2.5V reference, a CTR of 50% to 100% at 1mA, a 5000V RMS isolation voltage, a low temperature coefficient of 50 ppm/°C max, and is intended for use as the error amplifier/reference voltage/optocoupler function in isolated AC to DC power supplies and dc/dc converters.

This document introduces the features of FOD2743 optically isolated amplifier. This product is mainly used in ac/dc power supplies and dc/dc converters, with high precision, low temperature drift, high reliability and other characteristics.

This data sheet lists the technical specifications of FOD2743A/B/C, including reference voltage accuracy, current transfer ratio, isolation voltage, temperature coefficient, etc.
