NCP1607 Description
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...
