UCC28019A

Product Overview

UCC28019A is a Texas Instruments advanced continuous conduction mode (CCM) power factor correction (PFC) controller IC designed for high-performance AC/DC power conversion systems. The device uses average current mode control with a boost PFC topology to improve input power factor and reduce harmonic distortion. Featuring a fixed 65kHz switching frequency, enhanced startup performance, fast transient response and multiple protection functions, UCC28019A is suitable for universal AC input power supplies ranging from 100W to several kilowatts, including industrial power supplies, servers, telecom equipment and high-power adapters.
