Offline Controllers | NCP1360
概览
NCP1360 提供了一个新型方案，目的是在通用电源反激式应用中实现从几瓦到 20 W 的输出功率水平。由于采用新方法，此新控制器不再需要辅助反馈电路（光耦合器和 TL431 参考），同时可以实现优异的线路和负载调节。NCP1360 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检测，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谷开关可提供高能效。
