UCC2819 Overview
Description
The UCC2819/UCC3819 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.
Key Features
- The UCC3819 allows the output voltage to be programmed by bringing out the error amplifier noninverting input
- Available in the 16-pin D, DW, N, and PW packages
