TPS2376-H: What is the lowest input voltage TPS2376-H can be operated

Part Number:TPS2376-H

Hi,

Here are some questions:

1.  If use UVLO to set the operation voltage, what is the lowest operation voltage?

2.  Follow question1, what limit the lowest operation voltage? classifiation voltage range? Internal bias voltage requirement?

3. Datasheet page10. mantioned that 24V Vin would cause TPS2376-H classification circuits to dissipate power continuously, but 24V is out of classification voltage range, why it cause circuit to dissipate power continuously?

Thank you.

C.T.
