DC-DC Step-Up/Step-Down Module 5A 6A 3.3V–12V for Drone RC

DC-DC Step-Up / Step-Down Power Module — 5A & 6A, Multi-Voltage Fixed Output

Power your drone, RC airplane, or electronics project with rock-solid voltage regulation. This compact DC-DC converter comes in two variants — a 6A Step-Up (Boost) module and a 5A Step-Down (Buck) module — both delivering selectable fixed outputs of 3.3V, 5V, 9V, or 12V with industry-leading 92–94% conversion efficiency. Overtemperature protection, enable/disable control, and a wide operating range make these modules ideal for demanding RC, robotics, and DIY electronics applications.

Made in Mainland China.

Why Choose This Module?

• Multi-Voltage Flexibility: Switch between 3.3V, 5V, 9V, and 12V fixed outputs via jumper combinations — or dial in a custom voltage with the adjustable output option.
• High Efficiency (92–94%): Minimizes wasted energy and heat, keeping your build running longer on battery.
• Overtemperature Protection: Automatically reduces output current if the module runs hot, protecting your circuitry and components.
• Overcurrent Protection: Built-in current limiting (~10A on boost, ~6A on buck) safeguards downstream devices.
• Enable Interface: Low-level enable pin lets you switch the module on/off programmatically — perfect for microcontroller or flight-controller integration.
• Compact & Lightweight: Engineered for space-constrained builds like drones, RC aircraft, and embedded systems.
• Wide Temperature Range: Rated for -20°C to +85°C, suitable for outdoor and industrial environments.

Usage Notes

• Always verify positive (+) and negative (−) polarity before connecting — there is no reverse-polarity protection.
• For lower output ripple, connect an electrolytic capacitor in parallel across the input and output terminals.
• When operating at elevated temperatures or high load, provide additional airflow or a heatsink for best long-term performance.

Package Includes

• 1× DC-DC Step-Up or Step-Down Module (as selected)

Frequently Asked Questions

Q: What is the difference between the 6A Step-Up module and the 5A Step-Down module?

A: The 6A Step-Up (Boost) module increases a lower input voltage (DC 2.7V–13V) to a higher output voltage (up to 14V), making it ideal when your battery voltage is lower than the voltage your device requires. The 5A Step-Down (Buck) module reduces a higher input voltage (DC 5V–32V) to a lower, regulated output voltage (as low as 1V adjustable), perfect for powering 3.3V or 5V components from a higher-voltage source like a 2S/3S LiPo battery.

Q: Can I use these modules in a drone or RC airplane?

A: Yes — both modules are compact and designed to handle the power demands of drone and RC aircraft electronics. They support multi-voltage fixed outputs (3.3V, 5V, 9V, 12V) via jumper selection and feature overtemperature protection that automatically reduces output current to prevent damage during demanding flight conditions.

Q: How do I set the output voltage on these DC-DC converter modules?

A: The factory default output is fixed at 5V. You can change the output by configuring the onboard voltage jumpers to select 3.3V, 5V, 9V, or 12V fixed outputs. Alternatively, you can use the adjustable voltage mode to set a custom voltage within the specified range. Specific jumper combinations also allow intermediate voltages (e.g., shorting the 3.3V and 5V jumpers simultaneously on the step-up module gives ~7.2V output).

Q: Is there reverse polarity protection?

A: No — neither module includes reverse polarity protection. Always double-check that your input and output positive (+) and negative (−) wires are connected correctly before powering the module to avoid damage.
