Abstract
A circuit and a method for sensing a current flowing through a pass device of a voltage converter. The pass device is switchable between a conducting state and a non-conducting state. The circuit contains an output node for providing an indication of the current flowing through the pass device, a capacitive element, connected between the pass device and the output node. A first switching element is connected between the first terminal of the capacitive element and ground. A second switching element is connected between the second terminal of the capacitive element and ground. A control circuit controls the first and second switching elements to isolate the output node from the terminal of the pass device through the capacitive element while the pass device is in the non-conducting state.
