24V/12V to 5V 5A DC-DC Buck Converter Module with USB & DC Jack | Pro Tronix

Product Description

The 24V/12V to 5V 5A DC-DC Buck Converter is a highly versatile, high-current step-down power regulator designed for maximum connectivity and ease of use. It features a wide input range of 9V to 36V DC and steps it down to a stable, regulated 5.2V output, capable of delivering up to 5A (25W continuous power).

What sets this module apart is its user-friendly interface: you can power it via the blue screw terminals or the integrated female DC barrel jack. On the output side, you can tap into the regulated 5V rail using either the output screw terminals or the onboard USB Type-A female port. Utilizing highly efficient synchronous rectification, it converts power with up to 95% efficiency, keeping heat generation to a minimum. Additionally, it features an integrated fast-charge recognition IC, making it fully compatible with Android and iOS devices.

⚠️ Output Voltage Note: The output is designed to sit at approximately 5.2V rather than a flat 5.0V. This is an intentional design feature to automatically compensate for the voltage drop that naturally occurs over longer USB cable runs, ensuring your connected devices receive a full, stable 5V supply.

Connection Interface

This board provides multiple input and output pathways to suit different wiring needs:

• Input Options:

  • Blue 2-Pin Screw Terminal: Ideal for hardwiring bare wires directly from a 12V or 24V battery or industrial power supply.

  • DC Female Barrel Jack (5.5mm x 2.1mm): Perfect for plugging in standard, off-the-shelf 12V or 24V wall adapter bricks without cutting any cables.

• Output Options:

  • Blue 2-Pin Screw Terminal: Perfect for running jumper wires directly to breadboards, microcontrollers, or raw electronics.

  • USB Type-A Female Port: Ready for plug-and-play USB power cords to charge smartphones, power single-board computers, or run standard USB accessories.

Applications

• SBC Power Source: Powering heavy-load single-board computers like the Raspberry Pi 4 or Pi 5, which demand a high-current, stable 3A to 5A supply to run without performance throttling.

• DIY Smart USB Charger: Safely converting 12V car batteries, 24V truck batteries, or solar panel banks into highly efficient USB charging hubs for mobile devices.

• Robotics & Servo Power: Supplying heavy transient current to multiple high-torque 5V servos (such as MG996R) without causing your main microcontroller to brown out or reset.
