NCP1607 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.
General Features • “Unity” Power Factor • No Need for Input Voltage Sensing • Latching PWM for Cycle ...
