Abstract: Methods and apparatus are presented for sensing current flowing in a power transistor of a switch mode converter, in which a voltage is sensed across a first field effect transistor connected in a series circuit branch in parallel with the power transistor, and the sensed voltage is used to generate output signal to indicate the current flowing in the power transistor.
