The 1608B PWUH is an active power factor correction (PFC)controller specifically designed for use as a pre−converter in ac−dcadapters, electronic ballasts, and other medium power off−lineconverters (typically up to 350 W). It uses Critical Conduction Mode(CrM) to ensure near unity power factor across a wide range of inputvoltages and output power. The NCP1608 minimizes the number ofexternal components by integrating safety features, making it anexcellent choice for designing robust PFC stages. It is available in aSOIC−8 package
