NCP1607B 1607B SOP8
Cost Effective Power Factor
Controller
The NCP1607 is an active power factor controller specifically
designed for use as a pre−converter in ac−dc adapters, electronic
ballasts, and other medium power off line converters (typically up to
250 W). It utilizes Critical Conduction Mode (CRM) to ensure unity
power factor across a wide range of input voltages and power levels.
The NCP1607 minimizes the number of external components. The
integration of comprehensive safety protection features makes it an
excellent choice for designing robust PFC stages. It is available in a
SOIC−8 package
