L4986A ST Power Factor Correction | 10-SOP | 10V-22V Supply, 250kHz

Product Overview

The L4986A is a high-performance Power Factor Correction (PFC) controller from STMicroelectronics, designed for AC-DC converters requiring high efficiency and low harmonic distortion. It operates in Transition Mode (TM) with a proprietary constant on-time control, enabling high power factor and low THD across a wide load range. The device integrates advanced protection features and is housed in a compact 10-SOP package, making it suitable for space-constrained applications.
