Description

DESCRIPTION
The UCC3817A and the UCC3818A family provides 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 the ac input line voltage. Average current mode control maintains stable, low distortion sinusoidal line current.
FEATURES
Controls Boost Preregulator to Near-Unity Power Factor
Limits Line Distortion
World Wide Line Operation
Over-Voltage Protection
Accurate Power Limiting
Average Current Mode Control
Improved Noise Immunity
Improved Feed-Forward Line Regulation
Leading Edge Modulation
150-µA Typical Start-Up Current
Low-Power BiCMOS Operation
12-V to 17-V Operation
