Model UCC38503DW
Description PFC)，Texas Instruments Texas Instruments Integrated controller for power factor correction (PFC) pre regulator, and PFC converter can achieve approximate power factor and provide stable, low distortion sinusoidal line current. They utilize advanced features and innovative processes such as quantized voltage feedforward, current synthesis, frequency vibration, and conversion rate enhancement to provide significantly enhanced performance. ###Power factor correction (PFC), Texas Instruments PFC controllers comply with the IEC61000-3-2 harmonic current limiting standard. PFC controllers are designed for AC-DC applications, providing high power factor (PF), low current distortion (iTHD), high efficiency, and high power density.
