About this item

The 5A Constant Current/Voltage LED-Drives Lithium Battery Charging Module is a compact and versatile DC-DC buck converter that delivers both constant current (CC) and constant voltage (CV) control—ideal for safe and efficient charging of lithium-ion or lithium-polymer batteries, and for high-power LED driving. It accepts a wide input range of 4–38V and permits continuous, user-adjustable output voltage between 1.25–36V, with current up to 5A and power output to 75W. This module boasts high conversion efficiency—up to 95–96%—and operates at a switching frequency around 180–300kHz, enabling smooth and reliable voltage regulation. Built-in protection features include short-circuit limitation (up to 8A), over-temperature shutoff, and current limiting, ensuring robust safety during operation. Its durable, compact build (approximately 50mm × 26mm × 12–14mm, weighing 18–33g) makes it a practical addition to embedded systems, DIY electronics, solar setups, and battery-powered projects. In summary, this module offers a powerful, efficient, and safe solution for battery charging and LED power regulation—perfect for both hobbyists and professionals who need precise CC/CV functionality in a compact form.
