Overview

UNISONIC TECHNOLOGIES CO.
, LTD UC3854 Preliminary ENHANCED HIGH POWER FACTOR PREREGULATOR  DESCRIPTION The UTC UC3854 provide 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 AC input line voltage.
Average current mode control maintains stable, low distortion sinusoidal line current without the need for slope compensation, unlike peak current mode control.
Designed in UTC’s Bipolar process, the UTC UC3854 offers new features such as wide bandwidth, low offset Current Amplifier, a faster responding and improved accuracy enable comparator, a VR...
