概览

NCP1379 是高性能器件，旨在为准谐振转换器供电。该控制器利用专有的谷锁闭系统，可以在功率负载变轻时进行切换并降低开关频率。这样将产生稳定的运行，即使在漏极-源极谷中总是触发的开关事件下也是如此。此系统可在低至第 4 个谷的条件下运行，并在之后切换到变频模式，确保出色的待机功率性能。为了提高过载条件下的安全性，该控制器包括了过功率保护 (OPP) 电路，可对高电平线路处提供的电源进行箝制。具有安全功能的固定内部计时器依赖反馈电压来检测故障。一旦计时器过期，控制器将停止并进入自动恢复模式，以确保低占空比突发操作。该控制器特别适合电视电源应用，具有低启动电压，允许使用辅助电源为设备供电。
