Description

The UC3854AN /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. UC3854AN Features &bull; Controls Boost PWM to Near-Unity Power Factor&bull; Limits Line Current Distortion To <3%&bull; World-Wide Operation Without Switches&bull; Accurate Power Limiting&bull; UVLO Options (16 V/10 V or 10.5 V/10 V)&bull; 300-mA Start-Up Supply Current
