XL4015 5A Constant Current / Voltage LED Drives Lithium Battery Charging Module

The XL4015 5A CC/CV Buck Converter Module is a high-efficiency DC-DC step-down regulator designed for adjustable constant voltage (CV) and constant current (CC) applications. Built around the XL4015 switching regulator operating at 300kHz, it delivers up to 5A output current with efficiency up to 95%, making it ideal for lithium battery charging, LED driving, and embedded power supply systems.

Supporting a wide input voltage range of 5V to 32V DC and adjustable output from 0.8V to 30V DC, the integrated CC/CV control enables safe charging of Li-Ion and Li-Po batteries. Two onboard potentiometers allow independent adjustment of output voltage and current limit.
