Offline Controllers | NCP1340
概览
NCP1340 是一款高度集成的准谐振反激控制器，适用于设计高性能离线功率转换器。NCP1340 具有集成的有源 X2 电容器放电功能，可以实现低于 30 mW 的无负载功耗。准谐振电流模式反激级功能具有专属的谷锁闭电路，确保了稳定的谷开关。此系统可在低至第 6 个谷的情况下运行，并转换为频率折回模式以降低开关损耗。随着负载进一步降低，NCP1340 进入静音跳过模式来管理功率传递。为了帮助确保转换器耐用性，NCP1340 实施了若干关键保护功能，如内部欠电压检测、在任何输入电压下保证恒定最大输出功率的非功耗过功率保护 (OPP)、通过专门引脚实现的锁存过电压和 NTC 就绪高温保护，以及线路去除检测，可在去除线路时对 X2 电容器进行安全放电。
