TPS63805: TPS63805使用在5V转3V3的应用中时，测量到L1、L2两端的最低电压为负压，虽然负压的电压在芯片的耐受-3V以内，但负压持续时间可以达到200~300ns，请问这样的情况下会导致芯片损坏吗，还是说是正常的现象

Hello, above is the superimposed waveform of 200 test samples at the falling edge of SW2. As shown, there is a prolonged negative voltage. The PCB design follows the recommended guidelines.
