STMICROELECTRONICS L4984D Power Factor Correction IC
The L4984D is a line-modulated fixed-off-time control PFC pre-regulator IC designed for continuous conduction mode boost converters. Encased in a 10-pin SO package, it features proprietary modulation for fixed frequency, minimal total harmonic distortion, and high line and load regulation. Equipped with protection features such as overvoltage, feedback failure detection, brownout, and inductor saturation detection, it also includes a soft-start function and a gate driver capable of high current sourcing and sinking. Ideal for applications like high-power factor correction systems exceeding 1 kW, desktop and server power supplies, it ensures compliance with EN61000-3-2 and JEIDA-MITI standards, providing reliable, efficient power regulation in industrial environments.
