L4981AD013TR ST Power Factor Correction (PFC)

The L4981AD013TR is a Power Factor Correction (PFC) controller from STMicroelectronics, designed for high-power active PFC applications with average current control mode. For selection, verify supply voltage from 12V to 19V, 100kHz typical oscillation frequency, 5.1V reference voltage output, soft-start capability, and operating temperature from -25°C to +125°C. Features include average current mode control for near-unity power factor, wide range input voltage operation, low start-up current, overvoltage protection, feedback disconnection protection, and synchronization capability for multiple devices. Ideal for high-power switch-mode power supplies (SMPS) requiring active PFC (>200W), AC-DC adapters for computers and servers, industrial power supplies, electronic ballasts, and any off-line power converter requiring compliance with EN61000-3-2 harmonic current limits.
