With a 6V to 32V input range, the QC 3.0 USB Fast Charging Module DIY Step-Down Buck Converter outputs 24W for rapid device charging. Onboard logic identifies Qualcomm, Huawei, and Samsung fast-charge protocols for immediate handshake. Under the 34mm footprint, the converter fits custom power banks or automotive retrofits without bulk.
Key Features
- Protocol Detection: Integrated logic identifies QC 3.0, QC 2.0, Huawei FCP, and Samsung AFC. Fast charging triggers across multiple brands.
- Compact 34mm Build: Dimensions of 34x17x9.5 mm fit into small DIY project boxes. It fits inside tight solar setups.
- Safety Protection: Short-circuit and over-temperature sensors cut power during electrical faults. Hardware survives frequent local load shedding.
- High Efficiency: DC-DC buck step-down efficiency reaches 97% during 220 kHz switching. Minimal heat loss keeps components cool.
Frequently Asked Questions
How to use QC 3.0 module for solar charging?
Wire the solar panel DC output directly to the 6V-32V input terminals. The module stabilizes variable solar voltage into a fast-charge USB output.
What is the input voltage for QC 3.0 DIY board?
Operation requires a steady DC input between 6V and 32V. Input exceeding 32V results in permanent circuit damage.
