The XL6009 DC-DC Step-Up Boost Converter with Digital Display is a versatile and high-performance power module designed to increase a low input voltage to a stable, higher output voltage. At Electrapac, we recommend this specific version because it features an integrated voltmeter, making it a "smart" solution for field-testing and DIY power projects.

Product Overview

This module utilizes the XL6009 high-frequency switching chip, which is the superior successor to the older LM2577. It can take an input as low as 3V and boost it up to 35V. The standout feature is the 3-digit LED Voltmeter, which allows you to monitor your input or output voltage in real-time without needing an external multimeter.

Key Features for Electrapac Customers

• Integrated Digital Voltmeter: Features a bright red LED display. Use the onboard button to toggle between viewing the Input Voltage and the Output Voltage (indicated by "IN" and "OUT" LEDs).

• High-Frequency Switching: Operating at 400kHz allows for a smaller inductor and lower output ripple compared to older 50kHz modules.

• Wide Voltage Range: Boost a single Lithium battery (3.7V) to 12V, or a 12V car battery to 24V or 32V with ease.

• Calibratable Display: If the voltmeter shows a slight deviation, it features a calibration mode to sync the display perfectly with your professional laboratory equipment.

• Robust Terminal Blocks: Includes high-quality screw terminals for secure, solder-free wiring of your Electrapac components.

Setup & Safety Guide

To ensure the best performance from your XL6009 module, follow these Electrapac guidelines:

1. The "Boost" Rule: This is a Step-Up module only. Your input voltage must always be lower than your target output voltage.

2. Initial Calibration: Use the blue multi-turn potentiometer to set your voltage.

   • Clockwise: Increases Voltage.

   • Counter-clockwise: Decreases Voltage.

3. Thermal Management: For continuous loads exceeding 15W or 2A, it is highly recommended to stick an aluminum heatsink to the XL6009 chip to prevent thermal throttling.

4. Display Toggle: Press the button on the right side of the display to switch the voltmeter reading between the input and output rails.

Primary Applications

• Portable 12V/24V Power: Running 12V networking gear or LED strips from a 3.7V or 5V battery source.

• Solar Regulators: Boosting low-voltage solar panel output to a stable level for battery charging.

• Automotive Upgrades: Stepping up 12V vehicle power to 19V or 24V for specialized equipment or laptop charging.

• Lab Bench Tool: A portable, self-metered power source for testing sensors and microcontrollers on the go.

• Emergency Lighting: Powering high-voltage LED arrays from low-voltage backup batteries.
