One Board Does It All! XL6009 3A Boost Buck Converter, Handles Solar, Battery, Lab Power Conversion with Ease.

Key Features & Benefits:

True 4-Way Voltage Flexibility: Based on the XL6009 IC, it can Boost (step-up), Buck (step-down), or stabilize voltage. Input 3.8-32V, output an adjustable 1.25-35V. Perfect for variable sources like draining batteries or solar panels.

Robust 3A Continuous Output: Capable of delivering up to 3A sustained current with adequate heatsinking. Powers demanding loads like LED strips, motors, and multiple Raspberry Pis.

Tool-Free Voltage Adjustment: Simply turn the onboard blue multi-turn potentiometer with a screwdriver to set your exact output voltage. No programming required—ideal for quick prototyping and lab bench setups.

Built-in Essential Protections: Features input reverse polarity protection (safeguards against wiring mistakes) and over-temperature protection within the IC for basic project safety.

The Universal DIY Power Enabler: The core module for building adjustable lab power supplies, 12V/24V battery boosters, solar chargers, UPS for routers, and powering Arduino/Raspberry Pi projects from various sources.

Product Description:

Tired of juggling different converters for different voltage needs? This XL6009 module is the Swiss Army knife in your power toolkit. Whether you need to boost a fading 12V battery to 19V for a laptop, buck a 24V supply down to 5V for microcontrollers, or create a versatile bench power supply, this single board handles it all efficiently and simply.

🚨 Critical Notes Before Use! (Safety & Efficiency Guide)

⚠️ 【CORE WARNING: HEAT MANAGEMENT IS CRITICAL!】

The 3A rating is contingent upon excellent heat dissipation. Under high current (>2A) or with a small voltage difference between input and output, the chip will get VERY HOT. You MUST add a heatsink (sold separately) or active cooling for prolonged high-power operation. Without it, output will drop, the chip may shut down, or it can be permanently damaged.

❌ 【Output Voltage Setting Warning】

ALWAYS measure the output voltage with a multimeter BEFORE connecting any load, especially sensitive electronics like Arduinos, Raspberry Pis, or sensors! The potentiometer is sensitive. Incorrect adjustment can produce a voltage high enough to instantly destroy your devices.

✅ 【Input Voltage Golden Rule】

For stable Buck (step-down) operation, ensure the input voltage is at least 1V higher than your desired output voltage. For Boost (step-up), the input can be lower than the output.

🔧 【Efficiency & Current Calculation】

Efficiency is not 100% (typically 70-90%). Loss is converted to heat. Calculate required input current: Input Current ≈ (Output Voltage * Output Current) / (Input Voltage * Efficiency). Ensure your power source can supply this higher input current.

⚡ 【Non-Isolated Design Notice】

This is a NON-ISOLATED converter. The input ground (-) and output ground (-) are connected. Do NOT use in applications where galvanic isolation is required.
