This 25W DC-DC Step-Down Power Module is a compact 5A 350KHz 25V Buck DC to DC converter. The module with the GS2678 can convert any DC voltage between 3.6V and 25V into a selectable output voltage ranging from 3.3V to 25V (the input voltage must always be greater than the output voltage). You can choose the 5V direct output voltage using a convenient on-board switch or adjust it individually between 3.6V and 25V using the blue-white resistor. The module features three different output interfaces for comfortable and quick prototyping of projects. With the built-in on/off switch, you can easily turn the DC/DC converter on and off.
Note: The input voltage must always be higher than the output voltage.
