UCC28070APWR TI Power Management IC | 20-TSSOP | Dual-Phase, PFC Controller

Product Overview

The UCC28070APWR from Texas Instruments is a high-performance, dual-phase interleaved power factor correction (PFC) controller designed for AC-DC power supplies. It operates in continuous conduction mode (CCM) and provides near-unity power factor with low total harmonic distortion (THD). The device integrates advanced features such as frequency synchronization, overvoltage protection, and programmable soft start, making it ideal for high-power applications requiring efficient and reliable PFC.

Detailed Technical Specifications

Key Features

• Dual-phase interleaved operation for reduced ripple and smaller magnetics
• Average current mode control for stable and accurate PFC
• Programmable switching frequency up to 300 kHz
• Comprehensive protection: overvoltage, undervoltage, overcurrent, and thermal shutdown
• Low startup current and low quiescent current
• Frequency synchronization capability for multi-phase systems

Target Applications

• 5G base station power supplies (e.g., rectifiers for remote radio units)
• Industrial power systems (e.g., motor drives, welding equipment)
• Automotive on-board chargers (e.g., for electric vehicle charging)
