wer 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 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.
