Power Management IC Maximizes Energy Performance in Multi-Kilowatt SystemsTexas Instruments introduced a single-chip, interleaved power factor correction (PFC) control circuit for multi-kilowatt communications, server and industrial systems. In line-operated systems with power levels from 75W to 1 kW and above, the UCC28070 helps reduce total harmonic distortion, allowing systems to maximize usable outlet power and accommodate extreme variations and disturbances in worldwide AC line voltage levels. 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 unused phases of the power supply. In a 1.2 kW system, the company said the UCC28070 can initiate an increase of up to 1.5 percent efficiency at a light 20 percent load condition.
