一种同步整流器包括一个分立开关组件和一个用于控制分立开关组件的控制器，均安装在一个公共芯片托盘上，并且封装在单独封装中。分立开关组件和控制器共同封装在单独封装中，在精确的时间提供控制器端口与开关组件之间最短的连接路径，使控制器精确传感开关组件的电压，从而避免寄生电感效应，使控制器在精确的时间使能/禁止开关组件，从而改善功率消耗及更佳的工作效率。

A synchronous rectifier comprising a discrete switching device and a controller for controlling the discrete switching device both mounted on a common die pad and packaged in a single package. The packaging of the discrete switching device and the controller together in a single package provides shortest path of connection between the ports of the controller and the switching device at the precise time, resulting in improved power consumption and better efficiency.
