Abstract
A switch regulator module includes a switch and a current sensing module. The switch has an input port and an output port. The current sensing module senses a first voltage at the input port of the switch and a second voltage at the output port of the switch. The current sensing module generates a sense signal that is proportional to a current that flows through the switch based on the first and second voltages.
