Hello team,

Hope you are doing well. Please see below question from the customer and provide some feedback:

Using the TPS62056DGS in an application and the input voltage will be 3.5V.

It was unclear to me if this was sufficient to support a 3.3V output, i.e. the input will only be .2V above the output.

Can you confirm this is OK?

Please see section 9.4.4 in the D/S which discusses exactly this topic.

As well, this is a very old device. The TPS62160, TPS82150, and TPS62150A are much newer and preferred.
