2 Channel USB QC3.0 QC2.0 DC-DC Buck Converter Step Down

The 2 Channel USB QC3.0 QC2.0 DC-DC Buck Converter Step Down module is a highly efficient DC-DC step-down converter designed for quick charging applications. It allows you to step down a higher input voltage (such as 12V, 24V, or 36V) to 5V or 9V or 12V, providing a stable output voltage for charging devices that support Quick Charge 3.0 (QC3.0) or Quick Charge 2.0 (QC2.0). This makes it an ideal choice for charging smartphones, tablets, or other USB-powered devices quickly and efficiently.

Key Features:

• Dual USB Output Ports: The module features 2 USB output ports, allowing you to charge two devices simultaneously, ensuring fast charging for multiple devices.
• Supports QC3.0 & QC2.0: Compatible with Quick Charge 3.0 and Quick Charge 2.0 technologies, enabling faster charging speeds for supported devices. This is beneficial for reducing charging time and improving charging efficiency.
• Wide Input Voltage Range: Accepts input voltages from 12V to 36V, making it compatible with a wide range of power sources, such as car batteries, solar panels, or power adapters.
• Step-Down Conversion: The DC-DC buck converter steps down the high input voltage to 5V, 9V, or 12V outputs, ensuring that the voltage is regulated for optimal charging.
• Overcurrent and Overvoltage Protection: Features built-in protection circuits to prevent damage to the module or connected devices from overcurrent, overvoltage, or short circuits.
• Efficient Power Conversion: The converter operates with high efficiency (typically around 90% or higher), reducing power loss and improving the overall performance of the charging process.
• Compact and Portable: The module’s compact design makes it easy to integrate into various applications such as DIY power banks, in-vehicle chargers, or portable charging systems.

Specifications:

Applications:

• Smartphone Charging: Charge your smartphone, tablet, or other USB-powered devices at high speed, leveraging Quick Charge technology for faster results.
• Power Banks: Ideal for use in DIY power bank projects where multiple devices need to be charged simultaneously.
• Automotive Applications: Can be used in vehicles to convert car battery power (12V) into the required voltage for charging USB devices, ensuring convenient mobile charging on the go.
• Portable Power Systems: Perfect for solar-powered systems or off-grid applications, where you can efficiently step down the power from higher-voltage sources to power USB devices.

Usage Tips:

• Voltage Selection: When selecting the output voltage, make sure the connected device supports the chosen voltage. QC3.0 and QC2.0 devices are adaptive and will automatically adjust to the correct voltage, but other devices may require a fixed 5V output.
• Current Draw: Ensure that the current draw from both USB ports doesn’t exceed the rated output current of the module, which can typically provide up to 3A per port (depending on input voltage and converter specifications).
• Proper Heat Dissipation: When using the module at higher currents, consider adding heat sinks or ensuring proper airflow to prevent overheating.
• Avoid Overloading: Never exceed the input voltage or output current limits to avoid damaging the module or connected devices.

The 2 Channel USB QC3.0 QC2.0 DC-DC Buck Converter Step Down is a versatile and efficient charging solution for quick charge-enabled devices, ideal for use in various DIY power projects, vehicle chargers, power banks, and more.
