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.","metaTitle":"STMicroelectronics L4986B CCM PFC Controller, 10-SOP, Active","metaDescription":"STMicroelectronics L4986B CCM PFC controller, 10V-24.5V supply, 130kHz switching, -40°C to 150°C, 10-SOP package.
