LM2596 DC-DC Step Down Cc Cv Power Supply Module LED Driver Battery Charger Adjustable LM2596S Constant Current Voltage

Product details

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, DC Buck Charger LM2596 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. LM2596 Charge Module can charge most any size lithium-ion cells to almost any voltage you need. This is an inexpensive way to charge those 4.30v and 4.35v cells, as well as life 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.
