NCP1606
Cost Effective Power Factor
Controller
The NCP1606 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
NCP1606 minimizes the number of external components. Its
integration of comprehensive safety protection features makes it an
excellent driver for rugged PFC stages.
