CCM PFC controller — 130 kHz fixed switching, 10V to 24.5V supply
The STMicroelectronics L4986B is a Continuous Conduction Mode (CCM) PFC controller designed for power factor correction in AC-DC converters. It operates from a 10V to 24.5V supply rail and switches at a fixed 130 kHz. The 400 µA startup current keeps the bias supply small — useful when the auxiliary winding is still building voltage during startup.
Temperature grade and package — 150°C junction, 10-SOP footprint
CT suits prototype or low-volume builds.
