LM2596 DC-DC Buck Converter Step Down Module Power Supply Output 1.23V-30V

 Features:

• The highest output current is 3A which is not mean that it will always be 3A.
• When it output 3A, the max voltage is 3.3V. And the difference between the output and input can't be to much. The difference can't over 7V.
• And when output power is over 10W, you should use a heatsink.
• All SANYO solid capacitors, the 36u thickening circuit boards, high-Q inductance with output value of high-power  LED indicator.

Specification:

• Input: DC 3V to 40V (input voltage must be higher than the output voltage to 1.5v above can
• not boost)
• Output: DC 1.5V to 35V voltage continuously adjustable, high-efficiency maximum output
• current of 3A
• Dimensions: 45 (L) X 20 (W) X 14 (H) mm (with potentiometer)
