    LT3798
    Isolated No Opto-Coupler
    Flyback Controller
    with Active PFC
    DESCRIPTION FEATURES Isolated PFC Flyback with Minimum Number of
    External Components
    n V and V
    IN
    OUT Limited Only by External Components
    n Active Power Factor Correctio Low Harmonic Distortio No Opto-Coupler Required
    n Constant-Current and Constant-Voltage Regulatio Accurate Regulated Voltage and Current (В±5% Typical)
    n Energy Star Compliant (<0.5W No Load Operation)
    n Thermally Enhanced 16-lead MSOP Package The LTВ®3798 is a constant-voltage/constant-current isolated flyback controller that combines active power factor
    correction (PFC) with no opto-coupler required for output
    voltage feedback into a single-stage converter. A LT3798
    based design can achieve a power factor of greater than 0.97
    by actively modulating the input current, allowing compliance with most Harmonic Current Emission requirements. n The LT3798 is well suited for a wide variety of off-line
    applications. The input range can be scaled up or down,
    depending mainly on the choice of external components.
    Efficiencies higher than 86% can be achieved with output
    power levels up to 100W. In addition, the LT3798 can easily
    be designed into high DC input applications. APPLICATIONS Offline 5W to 100W+ Applications High DC VIN Isolated Applications
