Active, Not Rec
NCP1365 提供了一个新型方案,通用电源反激应用中比 20 W 略高几瓦的输出功率等级。由于采用一种新方法,此新控制器不再需要辅助反馈电路(通常为光耦合器和 TL431 参比),同时可以实现卓越的线路和负载调节。NCP1365 在高负载时以谷锁闭准谐振峰值电流控制模式运行,以提供高能效。当辅助侧功率开始消失时,该控制器将自动调节占空比,然后在更低负载下,该控制器通过谷开关勘测,以固定峰值电流进入脉冲频率调制。这种技术允许在微小的虚拟负载下保持输出调节。前 4 个谷中的谷锁闭可防止谷跳跃运行,然后在更低负载下的固开关可提供高能效。

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.)
