SY22471UAAC Boost PFC Regulator Datasheet
    Part NumberSY22471UAAC
    DescriptionQR, CV, Boost, Int. MOS 520V/9Ω single winding
    PackageSOT23-5
    Io_max (A)
    Input Type230Vac
    Po_max (W)25
    PF (>)0.9
    ApplicationPFC_Boost_CV
    • Integrated 520V MOSFET
    • Quasi-Resonant (QR) Mode to Achieve Low Switching Losses
    • PF>0.95, THD<10%
    • Output Over Voltage Protection 
    • Low BOM Cost
    • Compact Package: SOT23-5

    The SY22471U is a single-stage Boost PFC Regulator. Constant tON operation is applied to achieve high PF and no multiplier is need. Quasi-Resonant switching is applied to achieve high efficiency and better EMI performance.
