XL4015 5A DC-DC Adjustable Buck Converter
The XL4015 is a powerful step-down module designed for high-current applications. It functions as a non-isolated constant current (CC) and constant voltage (CV) regulator, making it an excellent choice for battery charging and driving high-power LEDs.
Key Features
- Dual Control Modes: Capable of regulating both Constant Current and Constant Voltage, providing flexibility for precision charging and power supply tasks.
- High-Efficiency Conversion: Achieves up to 95% efficiency using non-synchronous rectification and a 300KHz switching frequency.
- Robust Output: Delivers a maximum of 5A, though adding a heatsink is highly recommended when operating continuously at this peak level.
- Stable Power Delivery: Engineered with tight regulation (±0.5% load) and low output ripple (50mV) to protect sensitive downstream components.
- Compact Integration: Its 51mm x 26.3mm footprint allows it to fit easily into custom enclosures and industrial control boxes.
