PFC (Power Factor Correction) Controller ICs are active power management devices designed to shape the input current waveform of a switch-mode power supply (SMPS) to follow the sinusoidal AC line voltage waveform, maximizing power factor (approaching 1.0) and minimizing harmonic distortion. Active PFC is a regulatory requirement for power supplies exceeding 75W to comply with global standards such as IEC 61000-3-2.
PFC controllers operate in Continuous Conduction Mode (CCM) for high-power applications (kW range), Critical Conduction Mode (CrCM) or Transition Mode for medium power, and interleaved configurations to reduce ripple currents. Key selection specifications include switching frequency, line voltage sensing range, soft-start capability, overvoltage/undervoltage protection, and power efficiency metrics.
