Part Number: TPS568230

Hi team,

As you know the TPS568230 SW can survive -3v 10ns, but my customer's board is -4v, whether it has risks? Thanks.

Hi Frank

It is recommended to stay with in the datasheet recommendations. Do you have a boot resistor in the schematic that you could leverage?

Gerold

Hi Gerold,

The negative voltage is -4v, sorry for that. they didn't use a boot resistor there. Thanks.
