UCC28070能夠幫助設(shè)計(jì)師們滿足對(duì)功率要求非常嚴(yán)格的千瓦級(jí)電力系統(tǒng).此PFC控制器允許輕載相位管理以加強(qiáng)系統(tǒng)的性能，達(dá)到高于總負(fù)載范圍的高效應(yīng)用.相位管理可允許系統(tǒng)通打開或是關(guān)閉電力供應(yīng)的相位，所以僅用相位就可以激活. 在一個(gè)1.2千瓦的系統(tǒng)里，UCC28070可以在20％負(fù)載情況下初始化系統(tǒng)使效率高達(dá)1.5％，允許設(shè)計(jì)師們根據(jù)工業(yè)需求在指導(dǎo)說(shuō)明之上自行設(shè)置，如綠網(wǎng)、拯救氣候運(yùn)算方案和綠色創(chuàng)新工程.在20％的負(fù)載情況下，提供240瓦的電力供應(yīng)，這樣可以節(jié)省27％的電力.

The new UCC28070 two-phase, average current-mode controller allows designers to simplify power design, increase system reliability and achieve a greater than 0.9 power factor rating, which improves energy efficiency. See: www.ti.com/UCC28070-pr. The increasing need for better energy management is apparent in every area of our lives, especially at the business operations level. The magnitude of power requirements for data centers and telecom systems continues to drive industry-wide efforts to reduce wasted energy and improve power quality," said Bob Mammano, power management staff technologist and TI Fellow. "Today‘s announcement gives power engineers an innovative solution that raises the bar toward more efficient power supply control." Building on more than 20 years of PFC circuit development, TI‘s UCC28070 continuous conduction-mode controller provides unprecedented performance and reduces system cost in applications where high efficiency and high power factor requirements are important. These range from high-end communications systems to embedded white goods motor drives in refrigerators and air conditioners to HID lighting ballasts. Meeting Strict Efficiency Requirements The UCC28070 helps designers meet the most stringent efficiency requirements for multi-kilowatt power systems. This PFC controller allows light-load phase management to enhance a system‘s performance —— achieving higher efficiency over the entire load range. Phase management allows a system to turn on or off phases of the power supply, so that only the phases required to power the load are enabled. In a 1.2-kW system, the UCC28070 can initiate an increase of up to 1.5-percent efficiency at a light 20-percent load condition, allowing designers to exceed energy guidelines set forth by industry initiatives, such as The Green Grid, Climate Savers Computing Initiative and Project Big Green. In a 240-watt supply at 20-percent load condition, for example, this increase in efficiency results in a 27-percent power savings. [/color][/font]
