TPS62743: about the VIN

Hi Ti,

Our application is 3 AAA battery (0.9V~1.7V)  connect to TPS62743 VIN.

If  the VOUT  of TPS62743  is set as 3.3V, but when battery become empty, the VIN is lower than the VOUT .

Does it will cut off the output? or just output the voltage which is same as VIN?

Thank you!

Best Regards,

Scott
