TPS54260: VSENSE pin is opened

Part Number: TPS54260

Hi,

I am considering the operation when each pin of TPS54260 is opened or shorted.
What I want to ask is the behavior when the VSENSE pin is opened.
This is a state where the feedback loop is open, but what is the behavior of VOUT in this case?

Best Regards,

    When Vsense pin is open, the control loop thinks the output voltage is low. The feedback loop will try its best to drive the Vsense pin up, by driving the Vout to its max. So the behavior will be the device operates at maximum duty cycle and Vout is driven to close to VIN voltage.
