设计
NCP1342是一款高度集成的准谐振反激式控制器,适用于设计高性能离线功率转换器。NCP1342具有集成的有源X2电容器放电功能,可以在无负载时实现低于30mW的功耗。
NCP1342专有的谷值锁定电路,确保稳定的谷值切换。此系统可在低至第 6 个谷值时运行,并转换为频率折返模式以降低开关损耗。随着负载进一步降低,NCP1342将进入静音Skip模式来管理功率输出,同时最大程度地降低噪声。
为了确保高频率设计的轻负载性能,NCP1342采用最小峰值电流调制(MPCM),以快速降低开关频率。为确保转换器的耐用性,NCP1342 具备多项关键的保护功能,如内部欠压检测、在任何输入电压下保证恒定最大输出功率的无功耗过功率保护(OPP)、通过专用引脚实现的锁存过压和NTC就绪过热保护,以及线路移除检测,可在拆除交流线路时对X2电容器进行安全放电。
