LM2596 LM2596S DC-DC 3A 12/24V to 12/5/3.3V adjustable step-down power Supply module

  • Input voltage :3V ~ 40V 

  • The output voltage : 1.5V ~ 35V 

  • Output Current :3A( Max) 

  • Conversion efficiency:92%( MAX ) 

  • Output ripple: <30mV 

  • Switching frequency: 150KHz 

  • Working temperature: -forty Five~ +85 

  • Size :45mm * 25mm * 14mm(Long*Width*Hight) 

  • The range of input voltage: 3 V to 40 V dc (input voltage must be higher than to the output voltage of 1.5 V above. Can't booster) 

  • The range of output voltage: 1.5 V dc to 35 V voltage adjustable, high efficiency (92%) largest maximum output current is 3A. 

  • Power (3-40V), power indicator light, the module is working properly. 

  • Adjust the blue potentiometer knob (clockwise rotation generally boost,counter-clockwise rotationTurn down) and reach with a multimeter to monitor the output voltage required voltage.. 


  •  Current work long hours is recommended for use in less than 2.5A, while adding bulkHeat sink (10W output above),because it is the step-down module, in order to ensure stable output Set,please keep the minimum 1.5V differential.  


  • Weight: approx 100 g 

  • Material: Steel,Plastic
