UCC28019ADR General Description

The UCC28019ADR is an integrated circuit (IC) designed for power factor correction (PFC) applications in switch-mode power supplies (SMPS). It operates with a wide input voltage range, typically from 85V to 265V AC. This IC implements a critical conduction mode (CRM) PFC control method, ensuring high efficiency and low harmonic distortion. With its advanced features, the UCC28019ADR enables power supplies to comply with stringent power quality standards such as EN61000-3-2.Key features of the UCC28019ADR include an integrated high-voltage startup current source, which eliminates the need for external startup components, simplifying the design and reducing the overall system cost. It also incorporates a cycle-by-cycle current limit for overcurrent protection, enhancing the reliability of the power supply. Additionally, it offers comprehensive protection features like overvoltage protection (OVP), overcurrent protection (OCP), and thermal shutdown, safeguarding both the IC and the connected system from faults and failures.
