Hi Expert,
Our customer would like to configurate LM25575-Q1 to inverting buck-boost topology. They would like to know how to deal with Exposed Pad properly. Is it connected to GND internally? Thanks.

Hello
The EP is connected to the ground of the IC internal to the device.
So you must treat it as another ground pin.
In the case of the IBB it is connected to your negative output voltage.
For additional information, please see the attached application note.
Thanks
