XL6009 DC-DC Boost Converter – 5-Pack, 4A Output, 94% Efficiency for High-Performance DIY Projects
Need to step up a 5V source to 12V? Looking to power an LED strip from a 3.7V battery? The XL6009 boost converter is the ideal solution. This 5-pack ensures you have plenty of modules on hand for multiple projects, saving you the hassle of ordering individual units every time you start a new build.
Note: The output voltage must always be higher than the input voltage. This is a step-up (boost) converter, not a step-down (buck) converter.
Why choose this 5-pack? (Key Advantages):
- Great Value 5-Pack — Perfect for stocking up your workshop for multiple projects or having spares on hand.
- 4A Output Current — Delivers 33% more power than the classic LM2577 (3A), making it robust enough for DC motors, LED strips, and battery charging.
- Up to 94% Efficiency — Minimises energy loss, keeping the module cool even under moderate loads.
- 400KHz Switching Frequency — Nearly 8 times faster than the LM2577 (~52KHz), resulting in lower ripple (~50mV) and more compact passive components.
- ±0.5% Precision Regulation — Ensures stable output voltage even when the load current fluctuates suddenly.
- Low 18mA Quiescent Current — Highly efficient for battery-powered applications, preventing unnecessary power drain.
- Wide Operating Temperature (-40°C to +85°C) — Reliable performance in industrial environments, outdoor setups, or enclosed cases without active ventilation.
Technical Performance and Design
At the heart of the module is the XL6009 integrated circuit, which operates at 400KHz. This high frequency keeps output ripple to approximately 50mV under normal conditions, providing a cleaner voltage output than older generations without requiring extra external filtering. Voltage adjustment is handled via an integrated multi-turn potentiometer—simply rotate it to dial in your precise voltage, verified with a multimeter. An onboard 0.1µF output capacitor further suppresses high-frequency noise before it reaches your load.

Usage Instructions
- Connect your DC power source to the IN+ and IN- terminals.
- Before connecting your load, turn the multi-turn potentiometer fully counter-clockwise to start at the minimum voltage.
- Connect a multimeter to the OUT+ and OUT- terminals to monitor the voltage in real-time.
- Slowly rotate the potentiometer clockwise until you reach your desired output voltage.
- Connect your load and check for stability. Make minor adjustments if necessary.
- Ensure the output voltage is at least 1V higher than the input voltage for proper operation.
- When operating near the 4A limit, we recommend adding a small heatsink to the IC or ensuring adequate airflow.

Frequently Asked Questions
Can I use the XL6009 to reduce voltage (step-down)?
No. The XL6009 is exclusively a boost (step-up) converter; the output voltage must always be higher than the input. For reducing voltage, you will need a separate buck (step-down) module.
How does this compare to the LM2577 module?
The XL6009 provides 4A compared to the 3A of the LM2577, operates at 400KHz instead of ~52KHz, and produces significantly lower output ripple. This results in more available power, cleaner voltage, and better efficiency in a similar form factor.
Can I power LED strips or DC motors with this?
Yes. It is excellent for LED strips, low-power DC motors, Li-Ion battery charging, and development boards (Arduino, ESP32, Raspberry Pi, etc.), provided the total power draw does not exceed 4A.
Is additional cooling required?
For loads under 2A, the module runs cool without a heatsink. If you are pushing the limit towards 4A, we suggest attaching a small heatsink to the IC or placing the module in an area with good airflow.
Is the output voltage stable under varying loads?
Yes. With ±0.5% load regulation, the output voltage remains stable even when the current draw fluctuates, which is essential for sensitive circuits and microcontrollers.
