Description
The DC-DC Power Module 25W is a versatile 350kHz step-down buck converter designed to deliver stable power for electronics and robotics projects. It provides reliable voltage regulation with up to 5A output, making it ideal for makers, students, and hobbyists prototyping multi-voltage systems.
Wide step-down voltage range
The module accepts DC input voltages from 3.6V to 25V and steps down to an adjustable output between 3.3V and 25V. Because this is a buck regulator, the input voltage must remain higher than the desired output voltage.
High-current 25W power output
Operating at a switching frequency of 350kHz, the board provides a constant output current of 5A at 5V. It supports a maximum total output power of 25W to run demanding loads.
Flexible output voltage selection
You can select a direct 5V output using the convenient on-board switch or dial in custom voltages using the adjustable blue and white potentiometer.
Original voltage passthrough interface
An onboard Ovout interface routes the raw input voltage straight through to external components. This enables a single power supply to run high-voltage devices directly while the module steps down power for lower-voltage logic.
Integrated power switching control
The module features three distinct output interfaces to speed up project wiring. An on-board ON/OFF control button can be pulled high to activate the converter and low to shut it down.
Compact physical dimensions
With a footprint of 46 x 50 x 20 mm, this board fits easily into robotics enclosures and custom control boxes. The package includes one DC-DC power module.
