NCP1618 Datasheet (ON Semiconductor) - Multimode Power Factor Controller

NCP1618, Multimode Power Factor Controller

DATA SHEET www.onsemi.com High-Voltage, Multimode Power Factor Controller NCP1618 The NCP1618 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 incorporat
