TPS62130A-Q1: TPS62130A-Q1 absolute voltage over range. Is this case the problem?

Part Number: TPS62130A-Q1

Dear support member,

My customer created TPS62130A-Q1 bode.

Data sheet describe that SW absolute voltage is -0.3V to VIN + 0.3V.

Customer measured of created bode,
SW to PGND was -0.48V.

Is this case the problem?

Is there transient time of absolute voltage?


Best regard.

Bob Lee.
