Mini DC-DC 4.5-24V to 1.8-17V 3A Adjustable/Fixable Step Down Converter Module

This module is great for projects that need to regulate different voltage levels. Input any DC voltage signal and configure the board to output stepped down voltage that suits your project’s needs.

The input voltage ranges from 4.5 to 24VDC while the output ranges from 1.8 to 17VDC.  The maximum current this module can output is capped at 3A with some additional heatsink required. What makes this board stand out is its ability to give its user the option to either adjust the output voltage using the potentiometer or to fix the output to a desired voltage by cutting the trace on the backside of the board to the potentiometer and soldering the pad representing a fixed voltage you desire. (see image for example) The fixed voltage options are: 12V, 9V, 5V, 3.3V, 2.5V and 1.8V. 

(Turn clockwise to increase output voltage or counter clockwise to do reduce output voltage, if using the potentiometer)

This breakout board is also easy to connect. Please verify your input voltage goes in the “IN+” through-hole/pad and the GND goes into GND. Your output voltage is connected to the “VO+” pad and its ground is shared to the GND pad.

You also have the option to control the board by turning it on or off via a switch or microcontroller using the EN pad. The pad has an internal switch allowing the system to be on by default. By shorting this pin to ground, the system will automatically shut down saving power and current from your input source!

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