Overview of Texas Instruments UCC28810DR

The UCC28810DR from Texas Instruments is a power management device designed to provide efficient and robust solutions for power supply systems. This device is a flexible and feature-rich power factor correction (PFC) controller that is suitable for a wide range of applications, including LED lighting, LCD televisions, and power adapters. Its primary function is to enhance the power factor of the power supply by shaping the input current waveform to be in phase with and proportional to the input voltage waveform.

Key Features

• Highly Efficient Power Factor Correction: The UCC28810DR is engineered to achieve near-unity power factor, which minimizes reactive power in the system and improves overall efficiency.
• Advanced Control Method: It utilizes a fixed-frequency continuous conduction mode (CCM) which provides stable operation over a wide range of input voltages and output loads.
• Low Harmonic Distortion: The device ensures that the total harmonic distortion (THD) is kept to a minimum, reducing stress on the power grid and improving the quality of power delivered to the end device.
• Integrated Protections: The UCC28810DR incorporates various protection features such as over-voltage, under-voltage, over-current, and over-temperature protections to ensure the longevity and reliability of the power supply.
• Energy-Saving Standby Mode: A standby mode feature reduces power consumption when the load demand is low, making it an eco-friendly choice for energy-conscious applications.

Applications

The versatility of the UCC28810DR makes it suitable for a broad array of power supply applications. It is particularly effective in systems where power efficiency and power factor are critical, such as:

• LED lighting drivers
• Flat-panel television power supplies
• Power adapters for notebooks and other portable devices
• AC-DC power supplies for servers and telecom equipment

Technical Specifications

The UCC28810DR operates over a wide supply voltage range and is available in a surface-mount package that is easy to integrate into various circuit designs. It offers precise control to optimize system performance and meets regulatory standards for power factor correction.

In summary, the Texas Instruments UCC28810DR is a sophisticated and reliable PFC controller that offers high efficiency, low THD, and multiple protection features, making it an excellent choice for designers looking to improve the power quality and efficiency of their power supply systems.
