Which outcome occurs when a MOSFET, used within a high-frequency switching regulator, experiences a gate oxide breakdown?

💡 Explanation

Excessive gate voltage causes dielectric breakdown, creating a conductive path; therefore, uncontrolled current flows from drain to source because the channel is permanently open, rather than the transistor switching off, which would regulate the output.
