LM5145: SW voltage stress check

Part Number: LM5145

Hi team,

My customer is using LM5145 and they found that the voltage of SW is -7.79V with about 2ns during test. The waveform is shown as below, the per grid of abscissa is 20ns. They want to whether this voltage is safe for LM5145.

Thanks a lot.

        首先确认一下驱动和MOS是否有问题  ,  理论上MOS 体二极管有钳位作用.   同时也要确认测试准确度.

        或者你可以在SW脚接一个肖特基到GND看看效果?
