NCP1605 Datasheet PDF - ON Semiconductor

The NCP1605 is a controller that exhibits near unity power factor while operating in fixed frequency, Discontinuous Conduction Mode or in Critical Conduction Mode.

●Features |   | Benefits

●---|---|---

● | |  | |  |

● High Voltage Startup Current Source

●|   |

● Clean & lossless start-up sequence Less components

● Fixed Frequency, Discontinous Conduction Mode (DCM) or Critical

●|   |

● The best of the 2 modes: DCM to limit the maximum switching frequency and CRM to lower maximum current stress

● Soft-Skip during Standby Mode

●|   |

● Further reduced losses

● PFC ready signal

●|   |

● Suitable for topologies requiring limited input voltage range

● Fast Line / Load Transient Compensation

●|   |  

● Valley Turn on

●|   |  

● Output Under and Over Voltage Protection

●|   |  

● Brown-Out Detection

●|   |  

● Soft-Start for Smooth Start-up Operation

●|   |  

● Over Current Limitation
