L6561 ST Power Factor Correction IC | 8-DIP（0.300"，7.62mm） | 50kHz, 1.5A Gate Driver

Product Overview

The L6561 is a high-performance power factor correction (PFC) controller IC from STMicroelectronics, designed for use in AC-DC converters and power supplies. It operates in transition mode (TM) to achieve near-unity power factor and low harmonic distortion. The device integrates a 1.5A totem-pole gate driver, a precise voltage reference, and protection features such as overvoltage and overcurrent protection. Housed in an 8-DIP package, it is suitable for medium-power applications up to 300W.
