FEATURES

DESCRIPTION

Controls Boost PWM to Near-Unity Power

Factor

The UC3854A/B products are pin compatible

enhanced versions of the UC3854. Like the

UC3854, these products provide all of 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 the AC

input line voltage. To do this the UC3854A/B uses

average current mode control. Average current

mode control maintains stable, low distortion

sinusoidal line current without the need for slope

compensation, unlike peak current mode control.

Limits Line Current Distortion To < 3%
