5A DC-DC 24V/12V to 5V USB Buck Converter Module

5A DC-DC 24V/12V to 5V USB Buck Converter Module

Power your 5V USB devices from higher-voltage DC power sources with this compact DC-DC Step-Down Buck Converter Module. Designed for 12V and 24V systems, this module converts a DC input voltage into a regulated low-voltage USB power output.

With a wide 9V–36V DC input range, a USB output port, and additional connection options, it is suitable for DIY electronics, embedded systems, vehicle power projects and portable USB-powered applications.

The module features a compact PCB design with onboard power-conversion components, making it convenient to integrate into electronics projects where a lower DC voltage is required.

Key Features

• Wide Input Voltage: Supports DC input from 9V to 36V.

• Step-Down Conversion: Converts higher DC voltage to approximately 5.2V output.

• High Current Capability: Advertised maximum output current of up to 5A, subject to input voltage, load and cooling conditions.

• USB Output: Convenient USB connection for compatible 5V-powered devices.

• Multiple Connection Options: DC power connection and screw-terminal wiring options.

• Compact Design: Small PCB measuring approximately 6.3 × 2.7 × 1 cm.

• Wide Applications: Suitable for electronics projects, vehicle power systems and USB-powered equipment.

Technical Specifications

Typical Applications

• USB device power supply

• 12V and 24V DC power systems

• DIY electronics and prototyping

• Embedded electronics projects

• Vehicle USB power applications

• Portable power supply projects

• Microcontroller and development-board projects (where the required supply specifications are met)

Installation Instructions

1. Switch off the DC power supply before making connections.

2. Identify the positive and negative input terminals.

3. Connect a suitable DC source within the 9V–36V input range.

4. Double-check input polarity before switching on.

5. Connect a compatible USB-powered device.

6. Check the output voltage and temperature under load before continuous operation.

Important Precautions

• Use DC input only. Do not connect directly to AC mains.

• Observe the correct input polarity.

• Do not exceed the specified input voltage range.

• Do not assume the module can deliver 5A continuously under every operating condition.

• Provide adequate ventilation and avoid excessive heat.

• Check the actual output voltage before connecting sensitive electronics.

• This is a step-down converter; the input voltage must be higher than the required output voltage.
