Product Summary

The NCP1606B is an active power factor controller specifically designed for use as a pre-converter in electronic ballasts, ac-dc adapters and other medium power off line converters (typically up to 300 W). It embeds a Critical Conduction Mode (CRM) scheme that substantially exhibits unity power factor across a wide range of input voltages and power levels. Housed in a DIP8 or SOIC-8 package, the NCP1606B minimizes the number of external components. Its integration of comprehensive safety protection features makes it an excellent driver for rugged PFC stages. The applications of the NCP1606B include Electronic Light Ballast, AC Adapters, TVs, Monitors, All Off Line Appliances Requiring Power Factor Correction.
