PMIC - PFC (Power Factor Correction) from Unitrode : 4 - Page 1

Power Management ICs (PMIC) - PFC (Power Factor Correction) components are crucial in improving the power factor in electrical systems. These ICs optimize the phase difference between voltage and current, enhancing energy efficiency. They are widely used in applications such as industrial power systems, consumer electronics, and renewable energy installations.

By improving the power factor, these PMICs reduce energy losses and harmonics, leading to cost savings and prolonged equipment life. Leading manufacturers include Texas Instruments, Infineon Technologies, and ON Semiconductor.

These PFC ICs are essential for compliance with international power quality standards, making them indispensable in modern electronic design.
