PMIC – PFC (Power Factor Correction) is a type of power management integrated circuit designed to improve the power factor of electrical devices. It helps correct the phase difference between the input voltage and current, reducing energy losses and improving efficiency. The PFC circuit uses capacitors and inductors to smooth out the input current, ensuring it runs near the peak of the voltage waveform. This results in lower total harmonic distortion, reduced heat generation, and lower power consumption. PMIC-PFCs are commonly used in high-power applications such as computers, televisions, and industrial equipment.
