Power management IC'er til AC/DC forsyninger
Texas Instruments lancerer to nye power management IC'er til brug i 5- 100 W AC/DC strømforsyninger (in english).
Texas Instruments (TI) has 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.
