Abstract

A controller for a power converter includes: a first sense terminal and a second sense terminal for sensing an output voltage of the power converter; a bridging circuit configured to electrically couple the first sense terminal to the second sense terminal in a first state and electrically decouple the first sense terminal from the second sense terminal in a second state; and control circuitry configured to set the bridging circuit in the first state during a portion of a voltage ramp of the power converter, and to determine whether an open or short fault condition is present at either the first sense terminal or the second sense terminal based on a voltage across the bridging circuit in the first state.
