UCC2819, UCC3819 Power Factor Preregulator

UCC2819 Description

ą D Controls Boost Preregulator to Near-Unity Power Factor D World Wide Line Operation D Over-Voltage Protection D Accurate Power Limiting D Average C.
The UCC2819/UCC3819 provides all the functions necessary for active power factor corrected preregulators.

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
