TI Launches Green Rectifier™ Controller for 5V Power Supplies

TI Korea (CEO Jaejin Kim, www.ti.com/ww/kr ) January 4, 2011 – TI has released a power management controller/driver capable of driving standard and logic-level N-channel MOSFETs for low-voltage, secondary-side synchronous rectification. The UCC24610 Green Rectifier™ controller improves power delivery efficiency by up to 5% and reduces primary-side power loss in 5V AC/DC adapters and bias power supplies. (For more information on samples, technical documentation, and evaluation modules, please refer to www.ti.com/UCC24610-prkr )

The 600kHz UCC24610 Green Rectifier provides power savings and design flexibility not offered by conventional diode rectifier solutions. It also maximizes efficiency through features such as micro-sleep current, automatic light-load management, and synchronous wake-up. Utilizing drain-to-source voltage sensing, the UCC24610 supports various power architectures, including flyback and LLC resonant converters, offering designers greater flexibility.

Key Features and Advantages of UCC24610
• Small size and minimal number of external parts
• High Performance and High Efficiency: Micro-power sleep current, automatic light load management, synchronous wake-up function under light load conditions
backup
• System Protection: In the event of a short circuit or excessive “on-time” conditions, the device shuts down the MOSFET
• Design
