Controllers for power factor correction in pre-regulators and PFC convertors

RS Components now stocks Texas Instruments' integrated controllers for power factor correction in pre-regulators and PFC convertors which can achieve near unity power factor and give stable, low distortion sinusoidal line currents. The devices utilise advanced features and innovative processes such as quantized voltage feed-forward, current synthesis, frequency dithering and slew rate enhancement to provide significant performance enhancements.
