UCC2819

Power Factor Preregulator

UCC2819 Features

* such as lower start-up current, lower power dissipation, overvoltage protection, a shunt UVLO detect circuitry and a leading-edge modulation technique to reduce ripple current in the bulk capacitor. The UCC3819 allows the output voltage to be programmed by bringing out the error amplifier noninvert

UCC2819 General 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. Average current mode control maintains stable, .
