L4984DTR ST Power Factor Correction (PFC)

The L4984DTR is a transition-mode Power Factor Correction (PFC) controller from STMicroelectronics, featuring 800mA totem pole gate driver and advanced protection for high-efficiency power supplies. For selection, verify supply voltage range, low start-up current, operating quiescent current, adjustable frequency operation, voltage feed-forward for near-unity power factor, THD optimizer for low distortion, and operating temperature suitable for industrial applications. Features include overvoltage protection, feedback disconnect protection, disable function for standby operation, precise adjustable output voltage, and burst-mode operation at zero load. Ideal for power supplies with active PFC (>65W) requiring EN61000-3-2 compliance, AC-DC adapters, electronic ballasts, LED drivers, and flat-screen TV power supplies.
