NCP1632A CrM Power Factor Controller, Interleaved

onsemi NCP1632A Critical Conduction Mode (CrM) Power Factor Controller is an interleaving, 2-phase PFC controller. In heavy load conditions, the NCP1632A operates in critical conduction mode (CrM). The device can also operate in discontinuous conduction mode (DCM) with frequency foldback in light load for an optimized efficiency over the whole power range. The NCP1632A integrates a wide range of protection features for rugged operation. The device is ideal for applications where high-level efficiency over the load range and near-unity power factor are the key requirements.
