Name: LM2596S Step-down Module;
The input voltage: DC 3.2V~46V;
The output voltage: DC 1.25V~35V(Adjustable);
The output current: 3A (Max)
Conversion efficiency: 92% (highest);
The output ripple: < 30mV;
Switching frequency: 65KHZ;
Working temperature: -45℃~+85℃;
With power supply indicator light;
IN+ input positive; IN- input negative;
OUT+ output positive; OUT- output negative;
Input voltage range: DC 3.2V to 46V (input voltage must be 1.5V higher than output voltage. Can't booster);
Output voltage range: DC 1.25V to 35V adjustable, high efficiency (92%), maximum output current is 3A.
When 12v input, 5v output 1A current, load regulation less than 1%;
1.This is step-down module, the input voltage must be higher than the output voltage;
2.Output below 2A can work without heat sink, when output current more than 2.5A (or output power more than 10W) to work long hours please add heat sink.
3.Potentiometer adjustment: Clockwise voltage increases, counterclockwise voltage decreases. Rotate a circle about 1V.
