The UCC28610DR from Texas Instruments is a highly efficient, green-mode Flyback Power Supply Controller designed to manage and optimize power consumption for a wide range of power supply applications. This advanced controller is ideal for applications that require energy-saving features and high performance, such as consumer electronics, set-top boxes, LCD monitors, and standby power systems.

Key Features

• Green-Mode Operation: The UCC28610DR incorporates green-mode functionality that reduces standby power consumption to meet stringent energy efficiency standards. It achieves this by minimizing the switching frequency at light loads, which significantly reduces switching losses.
• Quasi-Resonant Control: This device employs quasi-resonant switching, which allows the power supply to switch at the valley of the resonant ring, thus reducing switching losses and improving overall efficiency.
• High-Voltage Startup: With an integrated high-voltage startup circuit, the UCC28610DR can start up efficiently from the rectified AC line voltage, eliminating the need for an additional standby power supply.
• Advanced Protection Features: The controller provides multiple protection features, including overvoltage, overload, and overtemperature protection, ensuring safe and reliable operation under various conditions.
• Frequency Dithering: Frequency dithering helps to minimize electromagnetic interference (EMI), allowing for easier compliance with EMI regulations.

Applications

• AC/DC Adapters
• Offline Power Supplies
• Consumer Electronics
• Standby and Auxiliary Power Supplies
