Undervoltage Lockout and Soft-Start
V
CC
undervoltage lockout (UVLO) circuitry inhibits
switching, forces VGATE low, and drives the DL output
high. If the V
CC
voltage drops below 4.2V, it is
assumed that there is not enough supply voltage to
make valid decisions. To protect the output from over-
voltage faults, DL is forced high in this mode. This will
force the output to GND and results in large negative
inductor current that pulls the output below GND. If V
CC
is likely to drop in this fashion, the output can be
