DC-DC 7V-28V to 5V 3A Fixed Step Down Converter Module

Need to supply your circuit/project with 5VDC but all you have at your disposal is a source between 7V-28VDC? This module without a doubt will help you do just that. This module allows anyone to input up to two stable DC voltage signals in the range of 7VDC -28VDC to in turn output up to two 5VDC signals. No matter the input, the output will always be fixed to 5V as long as the input stays in the specified range(1). The maximum outputted current can be as high as 2.5A prompting a heat sink requirement. (2)

This module is also very easy to setup. Just connect your input Voltage sources to the “Vin+” pads and their grounds to the “Vin-” pads. Your output Voltage source will be outputted through the “Vout+” pads and its ground reference will be the “Vout-” pads.

(1) Since there are two input pads offering the possibility to input two different voltage signals, make sure both voltages added together do not exceed 28VDC. Always stay below that mark. 

(2) It is strongly recommended you add some heatsink capabilities to your system when using this board to step down an input voltage higher than 10VDC.

*Note: This module is a step down converter! You cannot supply a low voltage and demand a higher voltage as the output.
