Hello Eddie,

What exactly is your question ?

My understanding is that you tried to run the system open loop without a signal on VINAC and VSENSE.

You will not get any signal on GDA or GDB until the signals on these inputs reach the minimum value specified.

The UCC28070 is behaving as expected.

Regards

John
