Introducing the UCC28060DR from Texas Instruments

Discover the UCC28060DR, a groundbreaking dual-phase, transition-mode Power Factor Correction (PFC) pre-regulator. This innovative component, crafted by the industry-leading Texas Instruments, is designed to enhance power efficiency and system performance in a diverse range of applications. The UCC28060DR is a testament to Texas Instruments' commitment to providing advanced solutions for power management challenges.

Key Features and Benefits

• Dual-Phase Operation: The UCC28060DR operates in a two-phase interleaved mode, which significantly reduces ripple current in the input and output, minimizing the size of required input and output capacitors and inductors. This results in a more compact, cost-effective power supply design.
• Transition-Mode PFC: Transition mode, also known as critical conduction mode (CrM), ensures high efficiency by adjusting the switching frequency in response to the load, leading to optimized performance for light to medium loads.
• Natural Interleaving: The device's natural interleaving technique ensures balanced current sharing between phases, which simplifies the design by eliminating the need for complex current-sensing circuits or external control.
• Advanced Control Features: The UCC28060DR is equipped with a suite of control features, such as soft-start, enable, fault protection, and overvoltage protection, which contribute to stable and safe operation under a variety of conditions.
• Robust Performance: With its built-in phase management, the UCC28060DR can operate with a single phase during low power conditions, enhancing light-load efficiency and extending the life of the product.
• Green Mode Operation: The pre-regulator supports green mode operation, which allows for reduced power consumption at light loads, making it an eco-friendly choice for energy-conscious applications.
