onsemi NCP1618DDR2G, PFC Controller, 130 kHz, 9.5 V 27-Pin, DIP

The ON Semiconductor NCP1618DDR2G 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. Housed in a SO-9 package, the circuit further incorporates the features necessary for robust and compact PFC stages, with few external components
