仔细看了他这个应用的说明:
It is important to note that the SHDN pin, while disabling the LTC4359 and reducing its current consumption to 9μA, does not disconnect the load from the input since Q1’s body diode is ever-present. A second MOSFET is required for load switching applications.因为Q1体二极管的存在负载和输入不会断开,需要增加第二季MOSFET来实现负载的开关应用

这个格式LTC4359的典型应用。。。。手册里的截图
如果是利用他的二极管导通,为什么不用二极管?IC还有什么用呢?请解释
