Description

The UC3854BN is an enhanced high Power Factor Preregulator provides 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 UC3854B 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. It is improved upon the UC3854 by offering a wide bandwidth, low offset current amplifier, a faster responding and improved accuracy enable comparator, a VREF GOOD comparator, UVLO threshold options (16/10V for offline, 10.5/10V for startup from an auxiliary 12V regulator), lower startup supply current and an enhanced multiply/divide circuit.
Controls boost PWM to near-unity power factor
Limits line current distortion to <3%
World-wide operation without switches
Accurate power limiting
Fixed-frequency average current-mode control
Low-offset current amplifier
Integrated current- and voltage-amplifier output clamps
Faster and improved accuracy ENABLE comparator
Green product and no Sb/Br
Device has limited built-in ESD protection, leads should be shorted together or the device placed in conductive foam during storage or handling to prevent electrostatic damage to the MOS gates.
