NCP1608 Critical Conduction Mode PFC Controller Utilizing a Transconductance Error Amplifier

PublishTime：2022-03-07

●The NCP1608 is an active power factor correction (PFC) 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 350 W). It uses critical conduction mode (CrM) to ensure near unity power factor across a wide range of input voltages and output power. The NCP1608 minimizes the number of external components by integrating safety features, making it an excellent choice for designing robust PFC stages. It is available in a SOIC−8 package.
