NCP1618HDR2G - High-Voltage, Multimode Power Factor Controller

Product Overviews

NCP1618HDR2G is an innovative multimode power factor controller. The circuit naturally transitions from one operation mode to another depending the switching period duration so that the efficiency is optimized over the line/load range. In very−light−load conditions, the circuit can enter the soft−SKIP mode for minimized losses.
