This DC-DC module uses the step-down switching regulator LM2596S to provide a stable power supply for the users. The output voltage is adjustable and can ensure 3A output load current. It works at 150 kHz and has high efficiency >90%.

• Input Voltage : 3V~40V (1.5V higher than the output at least)
• Adjustable Output Voltage : 1.5V~35V
• Output Current : 3A
• Dimension : 45mm x 20mm x 14mm

Pins :

• IN + input positive IN-enter negative
• OUT + output the positive OUT-output negative
• Note that the input and output can not be reversed. Reverse may burn out
