Overview of Texas Instruments UCC28060D

The Texas Instruments UCC28060D is a sophisticated dual-phase, transition-mode Power Factor Correction (PFC) pre-regulator. This integrated circuit is designed to provide high-efficiency power conversion with enhanced power factor and reduced total harmonic distortion, making it an ideal choice for a wide range of applications such as servers, telecommunication equipment, industrial systems, and white goods.

Key Features

• Natural Interleaving™ Technology: The UCC28060D employs Texas Instruments' proprietary technology to ensure automatic phase shedding and interleaving, which leads to reduced input and output ripple and extended life for downstream components.
• Advanced Current-Shaping PFC: It provides efficient power factor correction by shaping the input current to match the input voltage waveform, thereby reducing the total harmonic distortion and improving power quality.
• Multi-Mode Operation: The device supports both continuous conduction mode (CCM) and discontinuous conduction mode (DCM), which allows for flexible operation across different load conditions.
• Enhanced Efficiency: With its transition-mode operation, the UCC28060D achieves high efficiency at both high and light load conditions, which is critical for energy-saving and meeting various regulatory standards.
• Robust Protection Features: The chip includes a range of protection features such as over-voltage protection, under-voltage lockout, over-current protection, and thermal shutdown to ensure reliable operation under fault conditions.
