The IC will operate below 3.0 V, but will not meet the specifications.
No external DC loading is allowed at the BGBYP pin.
The maximum output current of 1.4 A is specified for V
The IC has an input peak current limit in which M1 is the current sense device
output current if the IC is in Boost mode
The maximum speed of change of a transient load should be 0.1 A/µs
