説明
- Reference Design based on NCP1937. It is a combination controller which integrates a power factor correction (PFC) and quasi resonant flyback controller in an SO-20 package. It integrates all the functionality necessary to implement a compact and highly efficient Switched Mode Power Supply for an adapter application. The PFC stage exhibits near unity power factor while operating in a Critical Conduction Mode (CrM) with a maximum frequency clamp
