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.
The document describes the FOD2743A, B, and C devices, which integrate an optocoupler, a precision reference voltage (2.5V), and an error amplifier in a single package. These components are primarily intended for use as the error amplifier/reference voltage/optocoupler function in isolated AC to DC power supplies and de/dc converters.
