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]
