UC3854A - Enhanced High Power Factor Preregulator

The UC1854A/B products are pin compatible enhanced versions of the UC1854. Like the UC1854, 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 correspo.

UC3854A Features

* Controls Boost PWM to Near Unity Power Factor

* Limits Line Current Distortion To
