Fixed 5V LM2596S DC-DC step-down power module BUCK 3A step-down module

Connection Ports:

IN + IN- input input positive and negative!

The positive output OUT + OUT- output negative

    Input voltage range: 7.0V to 46V DC is recommended to use in 40V! (Must be greater than the input voltage to output voltage higher than 1.5V. Can not boost)

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

Found 12V input, load regulation 5V 1A output current is lower than 1%

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

       Output 2A or less long period of time without additional heat sink output current is greater than 2.5A (or output power greater than 10W) to work long hours please add heat sink
