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
scheme that substantially exhibits unity power factor across a wide range of input voltages and power levels. Housed in a DIP8 or SOIC8 package, the NCP1606 minimizes the number of external components. Its integration of comprehensive safety protection features makes it a good choice for rugged PFC stages.
