Abstract:
In one embodiment, a power converter system includes a power device coupled between a first node and second node. The power device is operable to be turned on and off by a control signal. Current flows through the power device when the power device is turned on for delivering power to a load. A sensing circuit is coupled in parallel to the power device between the first node and the second node. The sensing circuit is operable to develop a signal indicative of the current flowing through the power device and is further operable to be turned on and off by the same control signal as for the power device. The sensing circuit turns on when the power device turns on and turns off when the power device turns off.
