By Technology
NCP1651 是一款有源功率因数校正控制器,可基于通用输入范围 (85 VAC- 265 VAC),在 50/60 Hz 电源系统中运行。它提供低成本、组件数量少的方案,用于具有中高输出电压要求的 AC-DC 转换器,简化了 50W - 250W 范围转换器对于 IEC1000-3-2 谐波要求的满足。NCP1651 为固定频率控制器, 驱动反激转换器拓扑结构以连续/非连续模式运行。它对平均输入电流进行编程,以遵循线路电压,从而提供统一的功率因数。NCP1651 使用平均电流模式控制 CCM 算法,有助于提供卓越的功率因数,同时限制了峰值主电流。其固定频率运行简化了输入滤波器设计。NCP1651 使用专属乘法器设计,比传统模拟乘法器的运行更准确。

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.)
