XL6009 5V-32V Input to 6V-48V Output Adjustable Boost Step-Up DC-DC Converter Module
This adjustable boost DC-DC converter module accepts 5V to 32V input and steps it up to any voltage from 6V to 48V using the onboard multi-turn potentiometer. Based on the second-generation XLSEMI XL6009 chip, it delivers up to 94% conversion efficiency -- significantly outperforming older LM2577-based boost converters. Its compact size and wide voltage range make it ideal for battery projects, LED drivers, solar applications, and more.
⚠️ Important: This is a boost (step-up only) converter -- the output voltage must always be higher than the input voltage. Do not exceed 32V input or 48V output. This module does not include short-circuit protection -- always install a fuse on the input side.
🔧 How It Works
- Connect your DC power source (5V–32V) to the IN+ and IN− pads on the module.
- With the output disconnected from your load, attach a multimeter to OUT+ and OUT− (set to DC voltage mode).
- Turn the onboard potentiometer with a small screwdriver -- clockwise to increase voltage, counter-clockwise to decrease.
- Once the multimeter reads your desired output voltage, connect your load to OUT+ and OUT−.
- Verify the voltage under load and fine-tune the potentiometer if needed.

📦 What's in the Box
- 1x XL6009 Adjustable Boost Step-Up DC-DC Converter Module
🛒 What You'll Need
- DC Power Source -- 5V to 32V (battery, wall adapter, solar panel, etc.)
- Multimeter -- to set and verify the output voltage
- Small Screwdriver -- Phillips or flathead to adjust the potentiometer
- Hook-Up Wire -- appropriately gauged for your current requirements
- Inline Fuse (recommended) -- for input-side short-circuit protection
🎯 Typical Applications
- Boosting battery voltage for portable electronics and field equipment
- Powering LED strips and LED drivers requiring higher voltages
- Stepping up 12V automotive power to 24V+ for accessories
- Adjustable bench power supply from a fixed DC source
- Solar panel voltage boosting for charge controllers
- Powering motors, solenoids, and relays that need higher supply voltage
- DIY and hobby electronics projects
💡 Tip: For best efficiency, keep the boost ratio (Vout ÷ Vin) below 4:1. For example, a 12V input boosted to 48V (4:1) will work but with reduced efficiency. A 12V input boosted to 24V (2:1) will deliver excellent efficiency. If you're drawing more than 1A continuously at high boost ratios, add a small heatsink to prevent thermal shutdown.
⚠️ Important Notes
- This is a boost-only converter -- output voltage must always be higher than input voltage (minimum ~1.5V difference).
- No short-circuit protection -- always install an inline fuse on the input side.
- No reverse polarity protection -- connecting input with reversed polarity will permanently damage the module.
- For loads exceeding 1A at high boost ratios, add a heatsink to prevent thermal shutdown.
- Always set the output voltage before connecting your load to avoid damaging sensitive electronics.
- Output ripple (~50mV) increases under heavy load -- add filtering for noise-sensitive circuits.
