Step-down Adjustable CC/CV Power Supply Module – LM2596 DC-DC


This LM2596 Module is perfect for LED driving and battery charging it is possible to regulate output current as well as voltage. Meanwhile, charge completion can be indicated by a designated LED light. Easily charge Lithium Ion and Lead Acid batteries with this module.


A low-cost high-amperage Switch mode DC/DC Buck supply with Constant Voltage (CV) and Constant Current (CC) output capability.

Get any voltage between 1.5V to 33V (Input voltage must be greater than output voltage)


  • Precision potentiometer for Output Voltage Adjustment
  • Precision potentiometer Output Current Limit Adjustment
  • LED indicator for Constant Current
