DC-DC Buck Converter 25W

The DC­-DC Power Module 25W is a compact 5A 350KHz 25V step down or Buck Converter from DFRobot. It can convert DC voltage between 3.6V-25V to a selectable voltage of 3.3V to 24V. This module features a switch for selecting between a constant 5V or a variable voltage determined by the potentiometer. The board also features terminal block that outputs (OVout) the original input voltage (OVin).

The DC­-DC Power Module 25W proves quite handy, for powering individual components requiring different voltages.

Note:

The ON/OFF button on the board can be pulled high to turn the converter module on and low to turn it off.

Caution: The input voltage must be higher than output voltage.
