description
The UCCx817/18 family provides all the functions necessary for active power factor corrected preregulators.
The controller achieves near unity power factor by shaping the ac input line current waveform to correspond
to that of the ac input line voltage. Average current mode control maintains stable, low distortion sinusoidal line
current.
