LM2596 LM2596S DC-DC 4.5-40V adjustable step-down power Supply module NEW ,High Quality

Large more favorable!

 IN + input positive-IN-input negative!

The OUT + output the positive OUT-output negative

  Input voltage range: DC 3.2V to 40V (input voltage must be higher than the output voltage above 1.5V. Could not boost)

 Output voltage range: DC voltage from 1.25V to 35V continuously adjustable, high efficiency (92%) of the maximum output current of 3A.

The measured 12V input, 5V output current is 1A load regulation of less than 1%

Note: This is a step-down module, the input voltage must higher than the output voltage.
