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. For samples, visit:
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.
Availability and pricingSamples and production quantities of the UCC28910 and UCC28630 will be available in
April 2014. Available in a 7-pin SOIC package, the UCC28910 is priced at
US$0.75 and the UCC28630 is priced at
US$0.60, in 1,000-unit quantities. The
UCC28630EVM are priced at
