onsemi NCP1606
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. Its integration of comprehensive safety protection features makes it an excellent driver for rugged PFC stages.- Min Voltage : 8.5V
