概览

NCP4306 是一款高性能驱动器，专用于控制开关模式电源中的同步整流MOSFET。高性能的驱动器和多功能性，使其可用于多种拓扑结构，如DCM或CCM反激、准谐振反激、正向和半桥谐振 LLC。

外部或固定可调的最小关断时间和最小开通时间消隐周期有助于对抗PCB布局和其他寄生元件引起的振铃。自同步功能保证了SR系统的可靠低噪音运行。NCP4306还利用MOSFET的驱动器开尔文连接，实现了满负载下的高能效运行，并利用轻负载检测架构实现了轻负载下的高能效。

驱动器精确的关断阈值、极低的关断延迟时间和高灌电流功能，可实现同步整流 MOSFET 导通时间最大化以及SMPS能效最大化。这种高精度驱动器和5V栅极钳位支持使用GaN MOSFET。
