XL4015 5A Constant Current / Voltage LED Drives Lithium Battery Charging Module is a linear module that has constant voltage and constant current function (CC CV) and it has a good performance. When you use it as a charger. this module use good chip as core and it is stable. also its ripple is low to 50mV.
This product is a 300 KHz fixed frequency PWM buck (step-down) DC/DC module, capable of driving a 0-5A (Max) Adjustable load with high efficiency, low ripple and excellent line and load regulation. Use as a step-down modules with overcurrent protection capabilities.
The DC/DC buck module has applications where the input voltage is higher than the output voltage , such as battery, power transformer, DIY adjustable regulated power supply, LCD Monitor and LCD TV portable instrument power supply telecom/networking equipment,24V vehicle notebook power supply, industrial equipment buck. 12V buck to 3.3V, 12V buck to 5V, 24V buck to 5V,24V buck to 12V, 36V buck to 24V etc.
This module has adjustable output Voltage and Current. Can also be used as a dedicated charger for Lithium Batteries (Li-Ion, LiPo) as it is capable of CC CV
Features:
- CC CV Adjustable
