App note: Diode turn-on time induced failures in switching regulators
Recently, switching regulator clock rate and transition time have become faster, making diode turn-on time a critical issue. A potential difficulty due to diode turn-on time is that the resultant transitory “overshoot” voltage across the diode, even when restricted to nanoseconds, can induce overvoltage stress, causing switching regulator IC failure. This video provides a testing methology enabling proper diode selection for switching regulators.
