Abstract
A clamp circuit generates a current limit for a DC-DC converter including an inductor. The clamp circuit includes a circuit to generate a control signal based on a sensed inductor current signal and a current limit signal for the DC-DC converter. A variable current source adjusts a first current signal based on the control signal. A transistor includes a control terminal, a first terminal and a second terminal. The variable current source outputs the first current signal to the control terminal of the transistor. The first terminal of the transistor outputs a clamp voltage signal.
