TI - Next-generation energy management IC

NewsSouth-East European INDUSTRIAL Мarket - issue 6/2007

Introduced as the first single-chip, interleaved power factor correction (PFC) control circuit for multi-kilowatt communications and industrial systems, the new UCC28070 has been unveiled by Texas Instruments. The device is a two-phase, average current-mode controller which allows designers to simplify power design, increase system reliability and achieve a greater than 0.9 power factor rating, which improves energy efficiency, says the company. Building on more than 20 years of PFC circuit development, TI’s UCC28070 continuous conduction-mode controller reduces system cost in applications where high efficiency and high power factor requirements are important, says the company. These range from high-end communications systems to embedded white goods motor drives in refrigerators and air conditioners to HID lighting ballasts. In line-operated systems with power levels from 75W to 1kW and above, the UCC28070 helps reduce THD, allowing to better maximize usable outlet power and accommodate extreme variations and disturbances in various AC line voltages.
