For our application we want to use yours ADP5024 and generate delay Between BUCK1 and BUCK2 Enable pin's.

As mentioned in the data sheet those pins are active logic level high  with Vih of min 1.1v.

Your ADP5134 has the feature of precision enable that controls the Enable pin voltage level using Hysteresis.

We want to know the behaviour of the power supply in the range of 1.1 to the high logic level apply on yours ADP5024 Enable pins.

This will direct us to delay the Enable pins using RC circuit.
