Abstract
A power converter with an isolated topology may include a power transistor, a sense transistor, and a read-out circuit. The sense transistor may be arranged in a current mirror configuration with the power transistor such that the gate terminal of the sense transistor is coupled to the gate terminal of the power transistor and the first drain/source terminal of the sense transistor is coupled to the first drain/source terminal of the power transistor. The read-out circuit may be coupled to the second drain/source terminal of the power transistor and the second drain source/terminal of the sense transistor. The read-out circuit may be arranged to cause a voltage at the second drain/source terminal of the sense transistor to be substantially the same as a voltage at the second drain/source terminal of the power transistor.
