This
LM2596
Constant
Voltage
/
Constant
Current
(CC/CV)
regulator
module
is
a
very
flexible
and
adaptable
charging
solution
that
can
provide
either
a
Constant
Voltage
(CV)
or
Constant
Current
(CC)
output.
With
a
variable
output
voltage
range
of
1.25V
to
30V
and
variable
output
current
from
0A
to
3A,
it
is
ideal
for
use
as
an
LED
or
laser
diode
current
source/driver,
a
battery
charger,
a
lab
current/voltage
source,
or
to
regulate
the
output
of
solar
panels
or
wind
turbines
to
charge
energy
storage
batteries.
It
can
charge
most
any
size
lithium
ion
cell
to
almost
any
voltage
you
need.
This
is
an
inexpensive
way
to
charge
those
4.30v
and
4.35v
cells,
as
well
as
LiFePo
and
many
other
cells
that
require
different
termination
voltages.
It
is
also
a
good
way
to
charge
smaller
cells
since
you
can
almost
infinitely
adjust
the
charging
current
and
output
voltage.

To
use
the
LM2596
CC/CV
Regulator
Module
as
an
LED
Constant
Current
Driver:
Make
sure
of
the
operating
current
and
maximum
operating
voltage
of
the
LED
you
will
drive.
With
no
load
connected
to
the
output
of
the
module
(open
circuit),
adjust
the
Constant
Voltage
potentiometer
CV
to
set
the
output
voltage
to
the
LED
maximum
operating
voltage.
Short-circuit
the
module
output,
and
use
a
multimeter
in
10A
current
scale
to
measure
output
short-circuit
current,
and
adjust
the
Current
Potentiometer
CC
to
set
the
output
current
to
the
required
LED
operating
current.
Connect
the
LED
to
the
module
and
test.
The
module
can
drive
multiple
LEDs
in
series,
parallel
or
in
series/parallel
strings,
as
long
as
the
maximum
voltage
and
current

the
string
does
not
exceed
the
30V
maximum
output
voltage
and

output
current
of
the
driver
module.
