    ■ ■






    ■ DESCRIPTIO The 8-pin LT ®1249 provides active power factor correction for universal offline power systems with very few
    external parts. By using fixed high frequency PWM current
    averaging without the need for slope compensation, the
    LT1249 achieves far lower line current distortion, with a
    smaller magnetic element than systems that use either peak
    current detection or zero current switching approach, in
    both continuous and discontinuous modes of operation. Standard 8-Pin Packages
    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 ...
