onsemi NCP1608
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.| Part No. | NCP1608 |
