L6561D ST Power Factor Correction IC | 8-SOIC | Transition-Mode PFC, 50kHz

Product Overview

The L6561D is a high-performance transition-mode Power Factor Correction (PFC) controller from STMicroelectronics, designed to achieve near-unity power factor in AC-DC converters. Housed in an 8-SOIC package, this IC integrates advanced features to simplify design and enhance efficiency. It operates in transition mode (also known as boundary or critical conduction mode) to minimize switching losses and reduce electromagnetic interference (EMI). The L6561D is ideal for applications requiring compact size, low cost, and high power factor, such as LED lighting, battery chargers, and power adapters.
