TPS54318 PH pin voltage over maximum ratings at switching dead time.
The dead time was about 20ns.
Maximum ratings are the following.
-PH: -0.6 to 7V
-PH 10ns transient: -2V to 7V
I tested with EVM.
Test condition was 5Vin, 1.8Vout, 3Aout.
PH pin voltage fall below -0.6V for about 20ns.
Is there possibility that the device is broken by this?
