Der LM2596 CV CC Laderegler Spannungskonverter basiert auf dem LM2596 von Texas Instruments in Kombination mit einem LM358 Operationsverstärker.

Das LM2596 CC/CV – Modul erlaubt die individuelle Einstellung von

• Spannung
• Strom
• Ladestrom / Leistung

mittels Potentiometer.

Mit einer einstellbaren Ausgangsspannung von 1,23V bis 30V und einem variablen Ausgangsstrom von 0 bis 3A (max.), eignet sich das LM2596 CC CV für ein weites Spektrum an Anwendungen wei beispielsweise

• LED oder Laser Treiber
• Akku Lader
• Labornetzteil
• Regler für Solarpanele oder Windräder zur Einspeisung von Akkus

Durch seine individuellen Einstellungen eignet sich das LM2596 CC CV Modul nahezu für jedweden Lithium Ion Akku. Das LM2596 ist eine kostengünstiger Laderegler und erlaubt neben der typischen 4,3 / 4,35V Terminalspannung die Einstellung auf jedwede individuell benötigte Terminalspannung.

Bei einem konstanten Ausgangsstrom von über 2A wird ein enstprechendes Kühlelement erforderlich (nicht im Lieferumfang enthalten).

The Voltage Converter is based on the LM2596 from Texas Instruments in Combination with a LM358 operational amplifier.

The LM2596 Constant Voltage / Constant Current (CC/CV) module is a very flexible and adaptable DC-DC converter 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 (max.), the LM2596 DC-DC converter is ideal for use as

• LED or laser diode current source/driver
• battery charger
• lab current/voltage source
• regulate the output of solar panels or wind turbines to charge energy storage batteries

The LM2596 CC CV Modul 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.

LM2596 LED Driver charger module

If the Output Current is over 2A a heat sink (not included) is required.

LM2596 CC CV Module Applications:

• High-power (up to 3A) LED or laser diode constant current driver
• Lithium battery charger 4V, 6V, 12V, 14V or 24V nickel cadmium or nickel metal hydride battery charger
• High conversion efficiency when used with car 12V battery input
• Adjustable laboratory voltage source or current source Dimming devices
• Regulate output of solar panels and wind turbines

LM2596 CC CV 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 of the string does not exceed the 30V maximum output voltage and 3A maximum output current of the driver module.

LM2596 CC CV Moduleas a Battery Charger:

• Make sure of the charging voltage and current of the battery you need to charge.
• With no load connected to the output of the module (open circuit), adjust the Constant Voltage potentiometer CV/OK to set the output voltage to the battery charge 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 expected charging current value.
• Charge transfer lamp (CH) current default value is 0.1 times the charging current (constant current value), For lamp current adjustment, turn middle Charging Convert Light potentiometer adjustment.
• Connect the module outputs to the battery and try charging.
