UCC2817 Datasheet PDF - Texas Instruments BiCMOS Power Factor Pregulator Specs

UCC2817 - BiCMOS Power Factor Pregulator

Datasheet Summary

Description

The UCCx817 and UCCx818 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.

Features

1 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.
Up to 18-V Operation.
Frequency Range 6 kHz.
