UCC2819 Product details

Description

The UCC2819/UCC3819 provides all the functions necessary for active power factor corrected preregulators.

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 noninverting input. Available in the 16-pin D, DW, N, and PW packages. block diagram VCC 15 OVP/EN 10 7.5 V.
