Switching Regulator
PF1105-01
SCI7630M Series
DESCRIPTION
The
SCI7630M
Series
offers
a
variety
of
high-efficiency
and
low
current
dissipation
switching
regulators
produced
by
the
silicon
gate
CMOS
process.(An
external
inductor
is
used
to
implement
the
boosting
function.)
Each
SCI7630M
basically
consists
of
a
reference
voltage
supply,
comparator,
and
inductor
driving
transistors.
Its
output
voltage
is
fixed
internally.
The
SCI7630M
Series
operates
with
low
current
dissipation
and
low
voltage.
Its
optional
features
include
voltage
detecting
function,
battery
back-up
function,
and
stand-by
function.
It
is
thus
suited
for
controlling
the
power
supply
of
portable
or
small
size
equipment
that
requires
high
operating
efficiency.
The
SCI7630M
series
has
four
major
variation.
The
SCI7631M and
the
SCI7638M
operate
by
the
clock
signal
generated
by
an
on-chip
CR
oscillation
circuit.
The
SCI7633M
operate
by
the
clock
signal
generated
by
a
crystal
oscillation
circuit.
And
another
feature
of
the
SCI7638M
is
its
output
voltage
which
has
temperature
characteristics
matching
the
properties
of
an
LCD,
making
it
suitable
as
the
power
supply
of
a
product
using
an
LCD.
