    U FEATURES
    ■ ■






    ■ DESCRIPTIO The LT®1248 provides active power factor correction for
    universal off-line power systems. By using fixed high
    frequency PWM current averaging, without the need for
    slope compensation, the LT1248 achieves far lower line
    current distortion with a smaller magnetic element than
    systems that use either peak-current detection or zero
    current switching approaches in both continuous and
    discontinuous modes of operation. High Power Factor Over Wide Load Range
    with Line Current Averaging
    International Operation Without Switches
    Instantaneous Overvoltage Protection
    Minimal Line Current Dead Zone
    Typical 250µA Start-Up Supply Current ...
