Chargeur Batterie Li-ion (LM2596)


Rupture de stock

LM2596 Constant current constant current voltage regulator. With finished charging LED indicator. Can be used as a variety of purpose. Eg, LED Driver, Lithium Ion/Lithium ion phosphate, NiMH, NiCD Battery charger

Basic principle of Usage:

Gives an input voltage of 5V-35V.
The voltage output is adjusted by turning the volt adj potentiometer, measured by a voltmeter at out+ and out-
The finished charging LED voltage threshold is adjusted by turning the finished charging LED adj potentiometer, measured by a voltmeter at out+ and out-
The maximum current is adjusted by turning the const current potentiometer, measured by connecting a current measuring voltmeter between out+ and out-.
Connect the device, eg. Battery or LED.
The module will regulate the output voltage, if the current drawn by the device is greater than the value setted, the current will be regulated instead of the voltage, constant current LED will light.
When the output voltage is greater than the value setted by the finished charging LED adj potentiometer, the finished charging LED will light.
