To verify the effectiveness of the above solution, tests were performed on the PMP40586 reference design platform. Figure 3-1 shows the waveforms for output short-circuit testing after optimization using the automatic mode switching capability. It is clearly shown that the maximum voltage stress across the SR is limited to 29.6V, which is significantly lower than the 69V (Figure 1-2) before optimization and is within the safe operating range of the device.
