LM2596 DC-DC 3A adjustable step-down power supply module, DC-DC Buck Converter.
DIY mobile power, communications equipment, power supply
· IN + input positive – IN-input negative!
· The OUT + output the positive OUT – output negative
· Input voltage range: DC 3V to 40V (input voltage must be higher than the output voltage above 1.5V. Module Could not boost the DC)
· Output voltage range: DC voltage from 1.5V to 35V continuously adjustable, maximum output current of 3A.
· The measured 12V input, 5V output current is 1A load regulation of less than 1%
· Dimensions: 45 (L) * 20 (W) * 14 (H) mm (with potentiometer), Smallest size you have ever seen, and with positioning holes, LED indicator DC-DC Module
Note: This is a step-down module, the input voltage must higher than the output voltage.
