概览

NCP1608是一款有源功率因数校正（PFC）控制器，专门用作AC-DC适配器、电子镇流器和其他中等功率离线转换器（通常高达350W）中的预转换器。它使用临界导通模式（CrM）来确保多种输入电压和输出功率下接近一致的功率因数。NCP1608集成了多种安全功能，最大程度减少了外部部件数量，是强固PFC级设计的绝佳选择。

  • 低于350W的PFC级

  • 固态照明
  • 电子镇流器
  • AC适配器
  • 电视机和显示器
  • 所有需要功率因数校正的离线设备
  • 电视机和显示器

  • 无输入电压检测要求
  • 高精度电压基准（±1.6%温度范围内）
  • 控制范围广，适用于大功率应用 (>150 W) 抗噪能力
  • 集成欠压和过压保护
  • 引脚对引脚兼容工业标准
  • 准确可编程的开通时间限制
  • 跨导误差放大器
  • 极低的启动电流消耗（<35µA）
  • 工作电流消耗典型值低（2.1 mA）
  • 拉电流500mA/灌电流800mA图腾柱栅极驱动器
  • 带迟滞的欠压锁定
  • 过流保护
  • 无铅无卤素

Re-calculate Data

Data is based on the following assumptions.

Note: The temperature and confidence level may be adjusted to your requirements.

Disclaimer: A reliability FIT rate calculated using this tool shall not be used for any functional safety purpose. In case a raw FIT rate needs to be estimated for a component which is targeted to be used in a safety critical application (i.e. compliant to ISO 26262 standard) it should be calculated according to generic safety standards (IEC62380, IEC61709, SN29500, FIDES, etc.)
