XL6009 DC‑DC Boost Power Module 4A High Current Adjustable Voltage Regulator DC Step‑Up Converter Module For Electronic DIY Power Supply Project

XL6009 DC‑DC Boost Adjustable Voltage Regulator Module

📌 Product Overview

The XL6009 DC‑DC step‑up adjustable voltage regulator module is a high‑performance BOOST power module with 4A switching current. This module adopts XL6009E1 second‑generation high‑frequency switching chip as the core component, delivering better comprehensive performance than the first‑generation LM2577 solution, featuring lower cost and higher conversion efficiency. It is widely applied for car power supply modification, industrial equipment power supply, electronic DIY projects, battery voltage boost and other power conversion scenarios.

✨ Core Features

• Wide input voltage range: 3V‑32V, optimal working input: 5V‑32V
• Adjustable output voltage: 5V‑35V (boost version); 1.25V‑35V (auto boost‑buck version)
• Built‑in 4A high‑efficiency MOSFET switch, maximum conversion efficiency up to 94%, higher than LM2577 (max 3A)
• 400KHz high switching frequency, supports small‑capacity filter capacitors, low output ripple, compact PCB size; LM2577 only works at 50KHz
• Auto boost‑buck version can stabilize fixed output voltage regardless of input fluctuation, perfectly solves vehicle power supply unstable problem during engine start‑stop
• Mature power conversion circuit design, good load regulation performance

📝 Operation Instructions

1. Connect input power to IN+ / IN‑ terminals, power indicator lights up for normal operation.
2. Adjust precision potentiometer: clockwise to raise output voltage, counter‑clockwise to reduce voltage, measure output voltage with multimeter to get target value.
3. If output voltage equals input voltage and cannot adjust: rotate potentiometer counter‑clockwise for more than 10 turns to restore normal adjustment function.
4. Long‑time continuous work: recommended working current ≤2.7A; maintain at least 1.5V voltage difference between input and output for stable performance.

⚠ Important Usage Notice

✅ This is boost module, output voltage must be higher than input voltage for standard boost version, do NOT use as step‑down module to avoid hardware damage. Kind reminder: If there are version differences or images not been updated, please refer to the actual product.
