The L6564D from STMicroelectronics is a transition-mode Power Factor Correction (PFC) controller IC, designed for high-efficiency AC-DC power supplies. Operating within a 10.3V to 22.5V supply range, it features a discontinuous conduction mode (DCM) with transition-mode control, ensuring optimal power factor correction and low harmonic distortion. Packaged in a 10SSOP surface-mount form factor, it is RoHS3 compliant and suitable for industrial and consumer applications requiring compliance with energy efficiency standards. With a low startup current of 90 µA, it minimizes power losses during initialization.
The L6564D stands out as a high-performance PFC controller with low standby consumption, robust transition-mode operation, and compact packaging. Its ability to deliver near-unity power factor makes it ideal for energy-efficient power supplies in industrial, consumer, and renewable energy applications. Compared to similar models, it offers better light-load efficiency and simplified design integration, making it a preferred choice for engineers prioritizing performance and compliance.
