onsemi NCP1601B
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. It simplifies the front- ended EMI filter design.| Part No. | NCP1601B |
