TI power management ICs deliver industry's highest efficiency and lowest standby power consumption for AC/DC power supplies

DALLAS, March 14, 2014 /PRNewswire/ -- Texas Instruments (TI) (NASDAQ:TXN) today introduced two flyback power solutions that achieve the highest energy efficiency and lowest standby power consumption for 5- to 100-watt AC/DC power supplies. The UCC28910 700-V flyback switcher and UCC28630 high-power, Green-Mode controller expand TI's leading portfolio of flyback controllers covering the complete power range of AC/DC adapters and power supplies used in personal electronics, printers, white goods and smart meters. 

Combining high density with high efficiency, TI's UCC28910 switcher with integrated high-voltage power MOSFET achieves the industry's best stand-by power consumption for 5- to 10-W designs and features the lowest constant-current output tolerance of 5 percent, providing an accurate, maximum current across different input voltages. Additionally, the UCC28630 controller's ability to support primary side regulation (PSR) technology improves reliability in 10- to 100-W power supplies.

The UCC28910 will be demonstrated in TI's booth #805 at the Applied Power Electronics Conference and Expo (APEC) in Fort Worth, Texas, March 17-19.

Key features and benefits of the UCC28910 and UCC28630:

• Highest efficiency: The UCC28910 achieves 80 percent average efficiency in 7.5-W designs and 78 percent efficiency at a 10 percent load. The UCC28630 achieves greater than 88 percent average efficiency in 65-W to 130-W designs, and industry-best 87 percent efficiency at a 10 percent load.
• Lowest stand-by power consumption: Meets and exceeds European Commission (EC) standby regulations, including the IPP 5-star mobile charger rating of less than 30-mW power performance for no-load, stand-by power and the EC Code of Conduct (Tier 1 and 2) for 5- to 10-W designs (UCC28910) and for 30-W designs (UCC28630).
• Improved reliability: Both flyback solutions support primary side regulation and eliminate the need for an optocoupler feedback circuit to increase reliability.
