NCP1601A Description
NCP1601A, NCP1601B pact Fixed Frequency Discontinuous or Critical Conduction Voltage Mode Power Factor Correction Controller The NCP1601 is a controller designed for Power Factor Correction (PFC) boost circuits. The device operates in fixed- frequency Discontinuous Conduction Mode (DCM) and variable- frequency Critical Conduction Mode (CRM) and takes advantages from both operating modes. DCM limits the maximum...
