bits
allow
V1,
V2,

to
independently
operate
in
either
skip
mode
or
forced-
PWM
mode.
See
the
REG1–REG4
Step-Down

Modes
section
for
more
information.
The
ARD_
bits
allow
the
output
voltage
to
be
actively
ramped
down
during
negative
voltage
transitions
See
the
Ramp-Rate
Control
(RAMP)
section
for
more
information.

that
this

is
not
required
