NCP43080 是一款用于开关模式电源的同步整流器控制器。该控制器可实现反激、准谐振反激和 LLC 拓扑结构的高能效设计。 外部可调节最短开关时间间隔时段提供了驱动各种 MOSFET 封装类型和 PCB 布局的灵活性。SR 系统的可靠低噪音运行由于自同步功能而得以保证。NCP4308 还利用驱动器到 MOSFET 的开尔文联接实现了满载下的高能效运行。 该驱动器精确的关断阈值、极低的关断延迟时间和高接受电流功能可实现最长的同步整流 MOSFET 导通时间。该高准确性驱动器和 5V 门极箝位使其非常适用于直接驱动 GaN 器件。 为了提供 PCB 布局方面的更大灵活性，此产品有两种版本。NCP4308 没有 LLD 功能，NCP43080 有 LLD 功能
