rising while below the UVLO threshold. EN is low.

DEFINITION
Normal operation
V
L
enters UVLO.
V
L
exits UVLO.
Resumes normal operation. DH1 and DL1 start switching.
DH2 and DL2 are off.
EN is pulled low and then high.
VOUT1 must reach 0V before restarting due to the cycling
of the enable in region H (above).
VOUT1 recovers.
VOUT2 recovers.
V
L
enters UVLO before VOUT2 fully recovers.
V
L
exits UVLO.
UVLO latches DL_ low.
Exiting UVLO: DL_ remains latched low until the first fall
of DH_ is detected.
DL_ is high after EN is pulled low and soft-stop is complete.
UVLO
Undervoltage threshold value is provided in the
Electrical Characteristics
table.
