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.

Claim (Index 10):
An integrated circuit, comprising:\n a first transistor having a first drain, a first gate, and a first source; a switch node coupled to the first source; an auxiliary circuit coupled in parallel with the first transistor, the auxiliary circuit including a second transistor having a second drain, a second gate coupled to an internal node configured to receive a constant voltage, and a second source coupled to the first drain of the first transistor; and a sense circuit coupled between the second source and the second drain of the second transistor, the sense circuit configured to generate a sense voltage representative of an auxiliary current to be conducted by the second transistor.
