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.
