ABSTRACT:
A current sensing circuit for use in a switching regulator having a high-side switch. The current sensing circuit includes a first sensing circuit coupled to the high-side switch for measuring current flowing in a positive direction through the high-side switch. The first sensing circuit includes a first replica device for generating a current which is a scaled version of the positive current flowing through the high-side switch. The current sensing circuit further includes a second sensing circuit coupled to the high-side switch for measuring current flowing in a negative direction through the high-side switch. The second sensing circuit includes a second replica device for generating a current which is a scaled version of the negative current flowing through the high-side switch.
