Abstract
A power source multiplexer includes a first switch circuit connected between a first input voltage source node and an output voltage node. A second switch circuit is connected between a second input voltage source node and the output voltage node. A driver circuit is configured to provide a steady-state current to drive one of the first or second switch circuits to electrically connect the respective input voltage source node to the output voltage node. A boost circuit is configured to boost the steady-state current for a switching time interval when switching from one of the input voltage source nodes being connected to the output node to the other of the input voltage source nodes being connected to the output voltage node.
