Abstract:
Features and advantages of the present disclosure include a switching regulator and current measurement circuit. In one embodiment, a switching transistor in the switching regulator has a first voltage on a first terminal and a switching voltage on a second terminal. A current measurement circuit has first and second input terminals. A first switch couples the second terminal of the switching transistor to the first terminal of the current measurement circuit when the switching transistor is on, where the second input terminal of the current measurement circuit is coupled to the first terminal of the switching transistor and measurement(s) may be taken. When the switching transistor is off, the first and second input terminals of the current measurement circuit are coupled together, and measurements emulate zero current through the switching transistor.
