FAIRCHILD SEMICONDUCTOR FOD2742A FOD2742B FOD2742C Manual(2)
The FOD2742A/B/C devices combine a precision 2.5 V reference, an optocoupler and an error‑amplifier in an 8‑pin SO package. They are intended for isolated AC‑DC power supplies and DC‑DC converters, offering tight reference tolerances (0.5 %‑2 %) and a low temperature coefficient of 50 ppm/°C.
Key electrical parameters include a current transfer ratio of 100 %‑200 %, 2.5 kV rms isolation, and operating temperature range from –25 °C to +85 °C. The datasheet provides absolute maximum ratings, pin definitions, and typical performance curves for design reference.
