L6561D ST Power Factor Correction IC | 8-SOIC | 10-22V Startup, 50-300kHz

Product Overview

The L6561D is a high-performance power factor correction (PFC) controller IC from STMicroelectronics, designed for transition-mode (TM) operation. It integrates advanced features to achieve near-unity power factor and low harmonic distortion in AC-DC converters. The device is housed in a compact 8-SOIC package, making it suitable for space-constrained applications. With a wide startup voltage range (10-22V) and programmable switching frequency (50-300kHz), the L6561D offers flexibility for various power levels from 50W to 400W.
