Dear Team,

Customer want to know what's the negative transient spec for SW node.

TPS62130 datasheet only have constant voltage spec.

They are looking for transient spec. like shown in TPS53318. ( -7V, <20ns)

Shaq,

Unfortunately, it is not specified. If you post a waveform, I can give you my opinion.

Hi Tucker,

Here is customer's waveform. There are 6.5ns duration lower than -0.3V.

Shaq,

That looks about normal. If you use a differential probe (preferred method) you will see it significantly reduced.
