Power supply control system

The invention relates to a power supply control system. In an example, a power supply control system for switchably routing at least a first power supply voltage to an output voltage supply node may include a first composite switching circuit. The first composite switching circuit may include a first field effect transistor (FET), wherein a drain of the first FET may be connected to a first supply voltage. The first combination switch circuit may further include a second FET, where a source of the second FET may be connected to a drain of the first FET, where a drain of the second FET may be connected to the output voltage supply node, where a gate of the first FET and a gate of the second FET may be connected together to form a first shared source node. The power supply control system may also include a first voltage drive circuit that may drive a "on" gate-to-source voltage level. 本公开涉及电源控制系统。在示例中，一种用于将至少第一电源电压可切换地路由到输出电压供应节点的电源控制系统可以包括第一复合开关电路。第一复合开关电路可以包括第一场效应晶体管(FET)，其中第一FET的漏极可以连接到第一电源电压。第一复合开关电路还可以包括第二
